Toyota - Corolla :: 1995 - Started Shuddering While Going Up Hills?
95 corolla 277k miles. 4 hours into a long trip went over a huge bump and the shocks seemed to "bottom out". Like they compressed as much as they could. Pulled over half hour later for a break.
After that drove rest of way home. Car started shuddering and slowing down going up a hill. Had to floor it just to get it to be 60 mph. Hill wasn't that steep. Seemed to do ok on flat parts.
Was a little low on gas so pulled over to fill up. Noticed car idled very roughly felt like it was going to stall while pulling into gas station.
Gas cap was a little loose. Didn't hear the whoosh of the vacuum you usually hear when undoing the gas cap either.
After that it seemed to be a little better going up hills. I drove it home, and a day later drove it and it seemed to go up hills ok.
It still idles very weirdly, roughly and like it's about to stall. While driving it sounds ok.
I was thinking fuel pump but now i'm not sure. It might be related to the gas cap, maybe the bump loosened it.
Camry :: Power Loss On 2003 XLE / Not Accelerating Or Going Up Hills
My 2.4L 03 XLE with 220k on it is losing power. Running fine other than not accelerating or going up hills as well as it was last week. I have P420 cat code for the past 40K. It also has the typical smoky start from leaking valve seals and uses about a quart every 1k miles.
Ran a can of 44k through it and I'm about to pull the plugs and see what shape they are in, but I'm wondering if this loss of power might be the cat. I've been searching and it seems a plugged cat is a common cause for power loss. Seems likely since I use so much oil.
Seen the DIY replacement and leaky seals Rockauto suggested replacement Eastern ECOIII as well as the Walker.
Ford Escape / Hybrid :: 2005 2.3L - Loss Of Power / Struggles On Hills
So my wife's 2005 escape has been slowly losing power over the past 6 months or so. I regularly change the oil, tried new spark plugs, new air filter and still it's lazy. I know it's not a race machine but it struggles on hills.
This winter it was having problems starting unless the accelerator was pushed to the floor. After a cleaning of the Idle control valve all was well again. It has roughly 72,000 miles on it and uses .5-1qt of oil between changes.
Subaru - Outback :: 2004 - Loss Of Power On Hills - Leaky Head Gasket?
My 2004 Subaru Outback has had the head gasket replaced, the O2 sensor replaced, spark plugs replaced. Still I cannot go up big hills anywhere near the speed limit. I think it may be the catalytic converter is bad from driving it with a leaky head gasket.

I have a 2000 Ford Explorer with 188,000 miles on it. I bought it used with 110K miles and put a new tranny in at that time. Now, I am having problems. I don't know if it's the tranny or the engine. It looses power when climbing hills. It takes off really slow with no power and finally gets up to speed it switches gears the whole time smoothly but the engine just can't take a load.
The check engine light came on and put out 10 codes:
P1451 EVAP Control System Canister Vent
P1747 Electronic Solenoid A-Short Circuit
P0743-Torque Converter Clutch Circuit Electrical
P0750-Shift Solenoid "A"
P0755-Shift Solenoid "B"
P0760-Shift Solenoid "C"
P0765-Shift Solenoid "D"
P0135-O2 Sensor Heater Circuit
P0155-O2 Sensor Heater Circuit
P1409-EGR Vacuum Regulator Circuit Malfunction
Those are the codes and I don't know how one has anything to do with the other. I checked the dip stick on the tranny and it's clean. Juicy red and not shavings.
Ford 6.7L Power Stroke Diesel :: 2011 - DTC P0401 / Significant Loss Of Power On Hills
Getting DTC P0401 on my 2011 with 92K miles. First time I got the CEL, we were on vacation, so I read the code, took a screen shot, then cleared it. Called my normal dealer, setup an appt, verified that they thought the truck was safe to drive. Coming home from vacation, I was pulling the TT in my sig, and noticed significant loss of power on hills that I have pulled many times before that I couldnt even hold 55 on now. Transmission dropped into 4th a couple times, on hills that it would sometimes stay in 6th, or at most drop to 5th.
CEL stayed off for a week , and came back on again. The funny thing is that after a day or 2, the CEL went back out on its own. I read the codes the P0401 is still there as a stored code(I did not clear this time). Around town the truck drives fine, the only thing I noticed was the decrease in power when towing. Truck is at the dealer now. TECH "isn't convinced" yet that there is a problem. He is not finished diagnosing yet, and I am sure that he has specific tests to run, but I am starting to fear that I will be getting the call to come get my truck.
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Power Loss While Towing Up Hills?
I pulled with my 2000 F250 7.3 for the first time yesterday pulling a 12,500 5th wheel and then again today with an 18 ft ski boat weighting around 3500 for both the trailer and boat. I had this same issue pulling both.
Today when pulling the boat/trailer i was behind a slow moving truck and when we hit a hill with a passing lane i merged over and wanted to start passing him. We started off at around 45 mph up the hill and as I started pushing the pedal I wasn't gaining any speed and my rpm's didn't even get over 1500. It felt like a stall and continued that at around 45-50 mph up the hill (about a 65 degree slope). When I'm not towing the truck runs great, plenty of power and averaging around 16 1/2 mpg.
Only mods i have is a 6647 Napa filter, muffler delete and it's running the same 4 position TS tuner from the original owner. During normal operation I run it at the 75hp gain and when towing i use the 50hp gain.
In both instances i could see black smoke coming from exhaust when pushing the pedal but my rpm's wouldn't go up and truck maintained the slow speed going up the hill. Once at the top it drove normal and picked up speed without any problems.
Town Car :: 1997 Town Car - Reset Actuator?
My 1997 Town Car has had the sound from the dash related to the blend door actuator in other posts. Noise would last for 5 - 10 minutes and go away. Today I noticed when driving I was getting a wild fluctuation in heat when set to automatic on the climate control so I decided to run the diagnostic to verify the blend door problem. I got code 024 so I know it is the actuator. My problem since I ran the diagnostic(exited by pushing defrost) the actuator noise is now constant and I have no heat, only cool air is blowing. Is there a reset I can do for the actuator? It's as if it is stuck in test mode.
View 8 RepliesFord :: Repeated Loss Of Coolant - Vacuum Cap Leak
I have a 2005 Ford focus. I haven't even had it 8,000 miles. THREE times it has overheated, and I've had to replace over a gallon of coolant. The first two times, the cause was a leaky 'vacuum' cap. The third time it was a different cap that was leaking. This radiator has two (that I know of) unused ports on it. A 3/8" one on the top left, and a 5/8" one on the bottom left. They are capped off with little rubber vacuum caps, which are quite simple to replace. But, these things don't last long before they start to weather and crack and leak. I just replaced them after 2,000 miles (before they started to leak), and they're already cracked. But oddly, only on the OUTSIDE. Inside they're still smooth and unbroken.
I've asked for advice at auto parts stores, mechanics, and even at a radiator shop. They all say they've never heard anything like this before?! I just got some silicone vacuum caps which are specifically rated for high temps, but they're so thin I'm not sure I wanna install them.
Civic - Honda :: 1995 - Shuts Off While Driving
About a week ago I was driving my 1995 Honda Civic, which normally runs GREAT, and in an instant and with no warning the check engine light came on, it suddenly lost power no matter how much gas I gave it, and it died going down the road. In the middle of the road I tried to crank it and it wouldn't crank. Very quickly the battery died and I wound up towing it to a service station. I thought, its got to be the alternator, right? But the mechanic said it was my battery not the alternator, so I replaced it, paying $145 for a battery change and a "diagnostics" test I probably could have done in the Autozong parking lot.. 'cept I'm a girl and I don't like to do those kinds of things. Anyway, battery in, all fixed I thought.
I drove it a week and made a 150 mile trip and in the last ten miles going down the highway at 70MPH, same thing. All of the sudden with no warning engine light comes on, it looses power no matter how much gas I gave it, I pull over and I'm stranded. I thought maybe it was the alternator after all, so I turned the lights and radio and wipers off (night and raining) and tried to crank it. It cranked up slowly after flooring it a few times, which really didn't seem to do that much like it would if it was flooded. Anyway, the car cranks, I drive a little further and again.. same thing. I pull over as I'm dying, repeat. Again, pull over, repeat. I tried several times to crank the car by popping the clutch like if the battery died, but that wouldn't crank it. I literally had to turn off the ignition switch, turn it back on and crank the car, then it would run another mile or so. After the fifth time pulling off the road I decided to put it in neutral, turn off the switch, turn it back on and crank it without even stopping and it worked until it shut off again with the same pattern as the first time. I finally made it home and got it to a service station today. I did notice that if I drove under 40MPH it would make it a short distance, but it did almost shut off twice while going to the service station.
I haven't heard back from them yet, I'm just wondering how scared I should be before I call them and i would like to have some knowledge since they told me once after diagnostics that it was the battery.
Trans Sport :: 1992 Pontiac - Huge Vacuum Leak And MPG Loss
One of the '92 Pontiac Trans Sports (3.1L V6 engine) had developed a huge thirst - the fuel consumption had doubled along with a serious loss of power. All ignition components - distributor cap, rotor, spark plug wires and oxygen sensor are new ACDelco's.
ECM is not throwing-up any fault codes but we suspect a vacuum leak since this engine runs better with the air intake covered-up almost completely.
Is there any way to trace and fix this kind of issue? Any vacuum diagram for this car - I couldn't seem to find it in the GM Service Manual... How would you suggest we proceed?
Celica :: 1995 Shuts Off While Driving When Gets Up To Operating Temperature
If I don't warm the car up, the car will drive longer. However, once it gets up to operating temperature, it shuts off. The temperature gauge doesn't indicate it is overheating, however if I turn my heat on full blast it does not shut off. I have replaced the fuel filter and spark plugs already and know it could be one of many things but am not sure where to start now.
View 3 RepliesVolvo - 940 :: 1995 - While Driving At Full Speed Shuts Off?
While driving full speed (55 mph), car shuts off. First RPMS drop to 1 - 1.5 (like being in neutral) then car shuts off -- no sputter or a cough, no rattle or puff of smoke, just kaput! If I try to restart immediately (after coasting to the side of the road) it turns over but won't start. Wait 60 seconds and it starts and drives normally. Have had it looked at, checked distributor cap, plugs, ignition coil and applied dielectric grease in case moisture was wreaking havoc in that area, but cannot find the source of the problem. Probably coincidental but it may happen more often in hot, humid weather?
View 4 RepliesChevrolet - 1500 :: Slight Rough Idle / Loss Of Power - Vacuum Leak
I have a misfire in the 6 cylinder on my 98 Chevy c1500 5.7l 350 v8 2wd. I changed the spark plugs and wires, cap and rotor, and changed the spider injector i put the spider injector in from another engine I had. After doing all this the code still comes up. The truck runs fine and except it idles slight rough not bad at all and now it says I have a vacuum leak and while I'm driving you can feel the loss of power. I tried all the ways to do it like on YouTube. What is wrong with my truck?

I have a 1995 Nissan Altima GXE 4cyl and it has been rough idling for a while now but now I have this new problem. While I drive the car and after it has warmed up, the car shuts off when I'm at a stop. When I'm at speed, it runs just fine and smooth and I only have problems at stops. I then restart the car just fine and continue driving. I'm having to keep doing this over and over. What could be the cause or causes for this?
View 4 RepliesFord Aerostar :: 1995 4.0 No Longer Likes To Shift Out Of First Gear / Vacuum Modulator Oddity
My '95 Aerostar 4.0 no longer likes to shift out of first gear. It will if I accelerate to maybe 25mph and completely get off the throttle for a few seconds. (It also revs freely at full-throttle kick down, as though it was in neutral.) A fluid and filter change didn't work, so I dug into forum posts. I found the vacuum modulator, and there's no ATF in the vacuum line, but it's an adjustable one which has me baffled...
The modulator has a thumb wheel on the outside of it. It will unscrew completely - and then it comes off, with a pin attached to it. This is very different from the ones I've seen pictures of here, where the pin is moved by the diaphragm. Is this the same pin, or some kind of preload device for the actual pin farther inside?
There's enough else wrong with the Aerostar that I'm not willing to sink very much more money into it. It'll run as is, as long as I'm careful. I'm just trying to get a few more miles out of it... might a regular, non-adjustable modulator?
Ford Super Duty (1999-2016) :: 2000 F250 V10 - Vacuum Loss Prevent 4x4 Lo Range Engagement
2000 6.8 v10 F250 supper duty crew cab. 4x4 high switch's on (manual lock hubs installed) but 4x4 low will not engage. Brake input/out put tested good. Trans switch Park/"N" both test good. PCM reads switch output in all modes, (dash 4x4 selector). The only other issue I am having is the Vacuum is bad ( defrost default no blend door operation). Would vacuum loss prevent 4x4 lo range engagement (with manual hubs ) or should I go to the solenoid, relays on the case/ right fender?
View 4 RepliesSaturn :: 1995 - Making Click Clack Noise While Accelerating Or Driving After Shuts Off Completely?
I just purchased a 1995 SL1. It has 95,000 on the car. It was a tow vehicle for an older man.It has an automatic transmission. It runs great but makes this funny noise. When you put the car in drive after having it completely shut off and after starting to accelerate to about 5 mph it makes a funny click clack noise followed by a beep. It does not sound mechanical but like a relay or something. It only does it once. As long as you don't turn the car off completely it does not do it again no matter if you put it back in park. If you turn the motor off and turn the key to ACC it does not do it. No other sounds at all. Transmission shifts fine. What it might be?
