Ford Ranger / B-Series :: 1994 V6 Engine Knock Under Load
I have a '94 Mazda B3000 3.0L V6. The engine finally gave out at 244,000 miles. I had a used motor installed with approx. 110,000 miles on it. I now hear a knocking sound only when the engine is under load (in gear and accelerating). The knocking is not present while revving the engine while in park or neutral. The transmission was rebuilt last year about this time. I have described this problem to several respected mechanics and they don't know what it could be. What could cause this condition?

My 1994 Aerostar, with 100,000 miles on it, started lurching at highway speeds. Weeks before this, the airbag light began blinking. The transmission man said it felt like it was shifting into overdrive, then out, then into overdrive, then out, etc.,etc. About this time, the cruise control quit being reliable. Dealership said codes didn't show a problem, "I must be mistaken". Then they said it sounded like a fuel filter.
View 6 RepliesGeo - Metro :: 1994 - Massive Oil Burning Under Load But Barely Any At Slow Speeds
I recently got my hands on a 1994 Geo Metro 1.0L 3 cylinder. Actually I got TWO of them. One had a bad engine (burned valves) but was otherwise a good car while the other was junk (expect for the engine) and I am amazed the suspension didn't separate from the body due to the rust. So, I decided to swap the engine from the junk car to the good car. I replaced all seals and gaskets external to the engine plus the PCV valve and gave everything else a good cleaning. The only seals and gaskets not replaced were the intake gasket, head gasket, and exhaust gasket as the engine was swapped in a complete manner. I also did the timing belt and water pump while I was in that far as well as did the plugs/wires/cap/rotor when putting it back in. I also ran an oil change through of cheap oil and some Seafoam and Marvel Mystery Oil to clean out any sludge as it looks like oil hadn't been changed real well in this engine. This oil came out pretty dirty after like 30 minutes of idling.
This little car runs amazing overall and keeps up with traffic and is way more peppy than I would ever imagine! It is also getting somewhere between 50-55 MPG and is fun to drive kinda like a big go kart. There is ONE MAJOR issue! If I get on a highway and try to maintain speeds of 65MPH or faster on big hills, I am guaranteed to get massive smoke clouds from the valve cover area filling with oil and puking it through the PCV/breather assembly right into the intake. I tried more oil changes with synthetic oil and this kept happening. I also ran Seafoam and MMO through the oil and drove it like 30 miles before the change. The oil came out really black each time. I can now actually see bare metal on the inside of the valve cover area through the oil fill where before it was all black after all these oil changes. I also replaced the PCV once again for good measure as it was like a $6 part.
I drove about 100 miles on the highway and started getting massive smoke screens every time I got a long uphill grade and tried to maintain speed, especially if I stayed in 5th gear. The car had more than enough power to make it up the hill in 5th but would smoke under the load. This began to make me suspect I had a serious blowby problem. I had a quart of oil in the car and added all of this during a couple stops on the way. I was at or slightly below the low mark when I decided to head home so I found a parts store and purchased a quart of the cheapest store brand 10W40 oil I could find and used this to get home. It still smokes quite a bit but maybe not like on the way there. I also had the wind at my back so I figured part of this was load dependent.
I was at or just below the fill mark on the dipstick when I got home so I added some more 10W40 oil I had sitting around for an ATV I no longer own. I know this is formulated for motorcycles and ATVs but figured I wouldn't hurt the engine any more. I also added some auto trans fluid as I know some people say the detergents in this can free stuck rings and work wonders in a neglected engine. Again, how can I do more damage to this engine than has already been done? The car calls for 5W30.
I have pretty much resigned myself to the fact that this little engine had 170K of not the best maintenance and is due for a rebuild. My plans are to keep driving the car while rebuilding the other engine with bad valves. I am glad I kept the old engine around. The car seems to be doing a lot better on the mix of thicker oil and ATF but wonder how long it can go like this. I took it out on the highway and really pushed it hard to see if I could make it blow smoke and it would not. It MAY have consumed some oil on the dipstick but I am even not sure about this. I am not adding any until I can see a definite drop in the level.
Here is my next question. What is likely the solution I found? Thicker oil sealing worn rings better? ATF dissolving crud around stuck rings? When/if I change the oil before I get to the rebuild, what weight should I use? 5W40 maybe? Also, these engines are notorious for burning valves if a thicker oil is used as the hydraulic lifters don't allow them to close completely.
Mazda - Engines - Noises - Mpv :: Car Started Whining Like A Jet Engine At Highway Speeds
A few months ago my car started whining at highway speeds. The noise has increased in pitch and volume, and is not dependent on engine speed--in fact, if I turn the engine off and coast, the whine persists, lowering in pitch (and getting quieter) when the car slows down. Recently the car has also started vibrating when I turn slightly to the right, as when I change lanes on the highway or bank right on a long turn (sharp right turns from a full stop don't elicit any noise). Do I have a problem with my alignment? I notice my tire wear looks a bit uneven.

We have had had our Santa Fe for a year, done 38000 km and love it. The car will start up and drive around town fine but as soon as the engine is under load at highway speeds or driving up a hill it loses all power.
In Automatic when this happens the gear will drop back to third. You can switch it over to manual mode and slowly accelerate back up to around 80-90km/hour with your foot flat to the floor but the rpm don't get above around 2000 to 3000.
If you stop and turn the engine off for a minute or so, when you start again everything will appear to back to normal but after another minute or two the problem will be back. The engine malfunction light comes on and sometime it's flashing but at other times it's constant.
The car's been in at our local Hyundai dealer for a week but at this stage they still can't quite figure out the exact cause of the problem. The code they pulled out suggested it was the exhaust particulate filter (apparently quite an expensive part) so they replaced that but it didn't fix it. They've also replaced the fuel filter and some temperature sensors that are part of the particulate filter apparently but still no joy.
Ford Ranger / B-Series :: Poor Acceleration / Considerably Slower To Come To Highway Speeds
A while ago I had a '99 Ranger. Long bed, regular cab, 2wd, 5-speed, 2.3. I had really poor acceleration. I was used to Toyota pickups with the 2.4 22RE, and the Ranger was considerably slower to come to highway speeds.
So, I took it to two different dealers, and they told me "that's just the way they are." I guess I believed them and sold the truck. Now, I am kind of thinking about another Ranger. Do people here think the '99 2.3 has an acceleration problem? Are there certain years to avoid the I4 in a Ranger?
Ford Ranger / B-Series :: 2003 - Lean Codes / Jerking At Highway Speeds
I've got a 2003 Ranger 2.3L DOHC, 5 speed, 2WD. It has a check engine light with codes :
P0316-Engine Misfire Detected On Startup
P0704-Clutch Switch Input Circuit Fault
P2195-O2 Sensor Excess Lean Signal Bank 1-Sensor 1
P0171-System Too Lean (Bank 1)
The truck runs fine when coasting or accelerating but when holding a steady light throttle to maintain speed the truck starts bucking and jerking. It's doesn't feel like a misfire, more like a fuel cut out condition. When this happens and you come to a stop, you can smell that the exhaust is very rich coming out of the tailpipe. I've already replaced the upstream O2 sensor and I did a tune up about 15k ago. I'm thinking fuel pump or fuel pressure regulator. I doubt if this is related, but on start up (more so on a cold start up) the A/C compressor clutch kicks in and out 3-5 times and makes a terrible racket.
Touareg :: Clicking Sound In Dash At Highway Speeds Like Solenoid Flipping On And Off
I did a search and see that this random clicking sound has been discussed but a source never identified. Thought I'd ask again 'cause mine is doing it more often and it's driving me nuts now that I hear it. Mostly at highway speeds, not tied to any particular function or steering wheel turning. It's like a solenoid flipping on and off. I know I could never get the dealer to replicate it and I assume if many Tregs have it, it's just a normal function but thought I'd ask.

I've got a 2000 Suburban 1500 4WD with the Auto 4WD. I'm running into a vibration at highway speeds along with a clicking sound at idle speed which speeds up and slows down with speed. I've discovered the u-joint on the front drive shaft where it connects with the transfer case is worn and has play in it. Could this cause the vibration?
Also, The front drive train spins any time the vehicle is motion, which is to say the front drive shaft spins as the truck goes down the road, correct?
Ford 6.7L Power Stroke Diesel :: 2012 - 3.31 Gearing Is Appropriate For Hauling?
I'm about to pull the trigger on a 2012 S.D. 6.7L 4x4 XLT Supercab Longbox seems all I can find is rigs with 3.31 gearing....I really want the 3.55 gears. Dealer is telling me the combination of the 6.7L with the new Auto Transmission is more than adequate for hauling. I will be hauling an Eagle Camp 950 Truck Camper along with a 10 foot toy hauler trailer....I'm not a freeway runner mainly secondary roads and mountainous terrain. I'm used to 3.73 gears and before than 4.10 gears.

View 8 RepliesFord Excursion :: Clicking / Tapping Noises On Startup?
My v-10 was clicking after starting (not the manifold or loose plug) until I hit the gas and it would go away so I figured I would start with an oil change and a new filter. Since I would have to drive 55 miles for a Motorcraft filter I headed for the auto parts store. I noticed on the box it said it had an anti-drain-back valve in it for startup. After some research I discovered these modular engines require that to keep the oil in the top end for start ups..................problem solved.
View 10 RepliesFord Transmission :: 1994 F150 - C6 Too Hot On The Highway?
I did a C6 swap on my '94 F150 4x4 recently to replace the M5OD the previous owner burned up. Just to check on things I hooked a brand new autometer trans temp gauge up to check out the temps. What I'm worried about is that on the highway (60-70 mph) it climbs up to 210*.
This was at night at about 75* outside temp. I know the C6 doesn't have a lockup converter, but these temps seem kind of high. It's not a heavy truck, not towing anything and I'm running stock sized 235's with 3.08 gearing.
For now I'm just using the internal radiator trans cooler, but I have a large factory bolt on cooler from an F350 of the same year that I plan on putting on. I have the gauge sender in the drivers side test port just in front of the shift linkage. I'm also running a deep pan that adds 2 quarts to the system.
Ford 7.3L Power Stroke (1999-2003) :: Tires Sound When Under Load At Speeds Above 37 - 40 MPH
The issue: when I reach 37-40mph I have a new sound which I believe is the transmission 4R100. It sounds like a flat spot on a tire, or the sound tires make when they leave the sticker on them. The cadence of the sound is slower than the rotation of the wheels.
If I let off the accelerator, the sound stops, as soon as I add load by pressing the accelerator the sound returns. If I shift to Neutral the sound is gone.
If I coast at any speed the sound is gone. It is only audible when under load at speeds above 37-40 mph. The cadence does increase as I speed up, but it doesn't sound as fast as the motor is turning (~1900 rpm's).
I monitor the truck with torque pro using the PIDs defined here on FTE. I can see lock-up in 3rd and the shift to overdrive. When in lock-up, I see 1-7rpm TCSlip.
Watching transmission temp as reported by torque, the hottest I see is 183* pulling an enclosed 6x12 @ 75 mph. Ambient temp is 95*. Excursion currently has 240k miles on the clock.
This sound was first heard by my wife two weeks ago. I thought I had tire issues and they needed to be rotated. The sound is still present, and now identified only when the truck is in drive, and under load, regardless of me pulling a trailer.
Yesterday on my 500 mile trip, the truck hiccuped several times which I believe was around the time I was either moving in or out of overdrive. Details in a different thread: [URL] .....
Anyway, I've looked at all culprits and can't find anything with the motor, or electrical system. I can't get to a transmission shop until Monday, and won't have my AE until I get home Sunday night. I have a 500 mile run tomorrow. I checked the transmission fluid and it's at a good level, pink, and doesn't have a bad smell.
Ford - F150 :: 1994 - CEL Came On For Around A Minute When Cruising Down Highway
I got a funny shifting issues that happens infrequently that I can no figure out. It happens after driving the car for a while on the highway, but not every time, and not just on the highway.
Here is my problem... when cruising down the highway the check engine light will come on stay on for a around a minute, the the check engine light will turn off, then of which my truck will lose power, not accelerate no matter how much I stomp on the gas, until my speed drops to under 55mph.
Once I get down to 55mph the truck will drop 2 gears into 3rd gear and then I can accelerate back up to speed. This will repeat every few miles. The computer will not store the check engine code, so no codes are pulled.
Dodge - Intrepid :: 1994 Won't Start Up Randomly - Die Under Load
Last weekend, the car wouldn't start after sitting for a few hours. After about 20 minutes it finally started. It has started and ran fine up until today. Same thing, it was parked for a while and wouldn't start. Then it did start, ran horribly, then died when it was put into gear. Then it started and ran just fine, my friend moved the car, parked it and turned it off and of course it wouldn't start after that.
I've done a lot of work to this car myself, including entire tune up, fuel filter, cam AND crank sensors (notorious problems on these cars), ignition switch, oxygen sensors, several other things in the past year or so. My only hunch is that it might be the auto shut down relay, but I'm not with the car so I can't test that. We had fuel pressure at the test port the first time this happened, so I wasn't really thinking it could be a fuel pump issue, but with over 210,000 miles anything is possible. Also, it sometimes dies when the car comes to a stop with the A/C on...but this doesn't happen very often.

View 10 RepliesGolf/GTI VII :: Strut Noises At Low Speeds
Hear struts on rough surfaces in parking lots or other rough surfaces at low speeds? It is something that I started noticing and I'm not sure if it is a standard VW thing or if it indicating some sort of premature failure. My previous car didn't do that (wrx) but I know every car manufacturer is a bit different.
Having gone through dealerships in the past for sounds that were not that loud I don't feel it is worthy of a dealership trip unless it gets more audible. They usually just say they heard nothing and everyone tells me I am ...
I want to get VWR springs but if I can hear the struts now it makes me wonder if it will accelerate failure. As stated above, I don't notice it at any normal driving speed, just slow maneuvering on rougher surfaces.
Nissan - Altima :: 1994 Jerk Whilst Driving Not Specifically Under Load
I have an automatic 1994 Nissan Bluebird which I think is equivalent to the Nissan Altima in the US.
My car seems to jerk whilst driving, not specifically under load. Sometimes when I'm in park with my foot on the brake, it feels like its very subtly jerking on the spot. It is a sporadic condition, sometimes my car won't jerk at all (or very few times) on the way to work, and other days it will jerk a lot. On the whole it seems to be getting worse though. When switching between gears when stopped it changes quite roughly (but not violently). Turning on the AC makes the condition worse. It has stalled once in reverse, and sometimes feels like it will stall again when I'm slowing down.
When it does jerk I can hear a noise that sounds faintly like a can of coke being opened (quick sharp pressure release), and it seems like something (possibly a belt) is losing traction/slipping and quickly regaining its grip. My first suspicion was the drive belt or one of the other belts slipping or something like that. Other possibilities I suspect are, from looking through the Hayne's manual:
-Something to do with the transmission (I checked the transmission fluid and it seems fine, very light brown but mostly transparent)
-Fuel filter clogged or fuel line problems (1.5 years ago the car wouldn't start, and a mechanic had to manually inject fuel through the injection nozzles. The fuel was near empty however)
-Spark plugs gap wrong or damaged
-Distributor components damaged (the distributor and alternator were changed last year and swapped in with 2nd hand parts, also the mechanic was very shifty and I think he hacked it into my car without too much care for good wiring, fittings, etc).
Also, I took the car to a mechanic last week and he thought it was the spark plugs, but I think the problem may be more serious than that. He also wanted to flush the transmission fluid but I think I will give this a miss since I checked the fluid and it seems fine, plus I heard flushing the fluid in an old car may have negative effects.
