Ford Super Duty (1999-2016) :: F250 - Skipping / Surging Under Load
I have a 99 f250 that seems like it has a bad coil, under a load it starts surging or bumping ( like it has in the past and I found a bad coil), I went through and unplugged each coil one by one while idling, couldn't find a bad one, so I bought a new coil and went through and rotated the coils, nothing worked, no check engine lights on.

I have an aftermarket single disk Cd player in my 2000 ranger. lately going over the smallest bump in the road causes the disk to skip. I can go over big bumps, train tracks etc... with no effects on the disk. Is it possible that the laser that reads the disk can be loose? Is it possible to tighten it? It doesn't affect the radio operation.

Well mine was. Checked all vac lines, 4wd was fine, tested with vac pump tested ok. So first I replaced the canister. Nope, actually happened more often. Pulled the 4wd solenoid that's mounted on the inner fender, rusted and split just above where the vac lines connect. I capped them and now my a/c is perfect, 4wd is out but for now I can live without 4wd.
View 3 RepliesAlero :: 2000 2.4 - Skipping And Rough Idle - Poor Gas Mileage
I have a 2000 Alero w/ 2.4 103,000 miles auto. I have been trying to fix a problem for about 3 months. It all started one night when i got stuck in my backyard in about a foot if mud. I thought i could drive it out, but when the wheels would spin and traction control would limit the rpms. After getting out the car would skip every now and then going up an incline at highway speeds in 4th gear (drive) then it would skip while idling. I could get it to run smooth if i hit the pedal and made it shift to 3rd. I drive this car daily and the problem has got worse slowly. Now its hard to crank and when it does there is a small amount of white smoke with strong gas smell while the motor spudders for about 10 secs.
It will finally "clear" up and still misfire every few secs or just cut off. Gas mileage is terrible between 15-18mpg. The engine light and trac off light has only been on twice. Both times the code was for random misfire of multiple cylinders. I have put plugs, boots (wires), distributor, 2 fuel processor regulator, seafoam, all octanes of gas, pulled injectors (looked ok a little dirty but still could be one) and I have ordered ignition control module. Its getting hard to drive and even harder to sell. It has just started the white smoke and gas smell and i think its that's the pressure regulator, but the skipping and rough idle....
Mercury - Sable :: 2000 - Power Loss / Engine Skipping And Catching Then Die
This first started happening about a year ago. started the car and it seemed fine to put it in gear to drive stepped on the gas and there was no power. the car moved forward slowly and felt like the engine was skipping and catching and then it would die. took it to the shop and it started right up first try for them. they drove it and it was fine. ever since then, it happens at random times on and off. I'm not sure if its bad fuel or something it just doesn't make sense to me.
View 8 RepliesFord Excursion :: Pinging / Spark And Knock Under Load At Higher RPM
So we finally found a travel trailer and picked it up yesterday. It is a 2008 Jayco 29A. Fiberglass with aluminum frame. 5345 dry weight, so shouldn't be too taxing on the Ex, but we towed it through parts of the NC mountains to get home and on steep grades it would downshift to 2nd gear and I would hear what sounded to me like pinging from the engine.
As far as I know the plugs are original, so should I just go ahead and replace them, or there also a possibility that this is just the notorious exhaust manifold leak? If all exhaust manifold bolts are still intact, is there a good test to know if it is the exhaust? No engine codes were thrown. The truck has 72k miles on it now.
Ford Excursion :: ABS Light / Speedometer Intermittent But Only Under Engine Load?
Just bought an '03 Excursion v10 with ~150,000 miles on it (Saturday morning). About 3/4 of my 1.5 hr drive home, when I hit my first small mountain, and I put my foot into it, the ABS light came on, and the speedo started bouncing around. Same thing on the second hill/mountain.
Then, after driving it on a couple small trips this weekend, and towing my 2500 lb boat home (20 min drive), it behaved fine (no big hills, etc). However, I decided to hookup my backup camera. During the 60 or so minutes that I had it sitting with dome lights on, etc measuring everything up (also trying to figure out how to fit my tool box in the back).
When I tried to start it when I was finished, it would just crank and crank and crank. Every now and then, it would try to catch, but never would. Left it sit for another 10 minutes and it started just fine. However, once it started, the ABS light came on for a little while, then went out.
At first, I thought "oh no... fuel pump". But then I started thinking about the speedo and the ABS light going whacko on the hills. I'm wondering if it's a low voltage issue? I had the alternator checked out today, and it tested fine at 13.9v. However, I've heard that those tests aren't always accurate.

Saturday I stuck the ex in a snow drift, rocked it back and forth in low range about six or seven times, once i got it out the engine shudders in overdrive. If i lock out OD it still shudders under load, It starts at around 40 mph, if I push it up to 60 and let off the throttle it stops and is smooth until I start to climb a hill. It never did this before It is a 2001 V10 with 143,000 miles, where to start looking ....

My 2012 Prius makes noise in cold days. After careful examination I found the noise comes from the rubbing between the joystick cover and the center console bridge cover. If I press the joystick cover with my fingers, the noise will be significantly reduced or even eliminated. So I think if I put a layer of soft material there, I may be able to eliminate the noise. How to remove the center console bridge cover? Either pictures or video will be great.
View 1 RepliesFord Excursion :: Turbo Surge - Cannot Maintain 70 Mph With Small Load Up A Mild Hill
I have a 2002 EX 7.3 and have never towed anything with it since purchased a year ago. This weekend I towed a side by side on a single axle trailer about 400 miles and could not maintain 70 mph with the small load up a mild hill. Also I could here the turbo surging while climbing hills. I have a AFE cold air intake and that is it. Truck had a aftermarket muffler on it when I bought it. New to the diesels but I thought it should tow that Trailer a little easier. I have no boost gauge or anything. Truck runs great other then this issue. Does not burn oil, get hot or anything out of the ordinary.

2000 Explorer Sport 4.0. I just did the heads, valves, decked, proofed. New wires, plugs. Followed the procedure to the letter. First two starts were a bit touchy, but now starts fine and purrs like a kitten at idle. The problem; under load it acts like it drops a cylinder. Bad plug, bad wire, fouled injector? This thing is driving me nuts.

View 5 RepliesFord Super Duty (1999-2016) :: 2000 F350 - Grinding From Front Axle When In Gear / Under Load
The issue is with my 2000 F350 crew longbed V10. Other than a BTS trans put in a little over a year ago, and FoMoCo motorsports headers, the whole truck is bone stock. Oh, it has that fantastic auto-hub thing with the fake locking hubs and the little switch on the dash (I'd love to convert it to a manual shifter...?). 174k on chassis, so things need to be done, 40k on engine, 3k on BTS 4r100.
Yesterday I was running around town, made a stop, and when I started moving again got a loud grinding from the front axle. Thought maybe I'd picked up a rock in a caliper or something, so I jumped out and checked everything, no joy. Moved forward, there it is again. No vibration, but loud enough (or telegraphing enough) to hear clearly in the cab. Let the truck roll forward, popped in to neutral, noise fades away. Back in to drive, there it is. So, now I know it's trans/t-case/driveshaft/related. I recently put new vacuum lines in, checked all the connections, and pulled, cleaned and lubed the hubs.
And since the trans is a nearly new BTS that is working just find, I'm narrowing the search to the hubs, drive shaft, t-case.
Get home (noise abates above 30mph, or everything else drowns it out), crawl under, and find the front driveshaft is locked. Ok, stuck hub? Pull out both the fake locking hubs, and now the shaft turns. I can turn each front axle by hand at the u-joint, and I kinda hear a faint grinding on the right side (will bad needles make noise only under a load from the trans and not coasting in neutral?), and when I swing the drive shaft around the left axle moves, right doesn't, etc etc.
I'm going to pull the drive shaft today and check the U joints, and drive a bit to see if the noise is still there, but I am thinking I might have some bad needles on the pax side axle...
Ford Super Duty (1999-2016) :: 2000 F250 - Vibration When Accelerate Pretty Much Any Load Above 1200 RPMs
I have a 2000 f250 crew cab short bed 7.3 on a 6inch bds lift and 37 inch tires. When I accelerate pretty much any load above 1200 rpms I can feel a vibration, kinda feels like it may be coming from the front left but I'm not sure. I have heard that a wheel bearing going out can cause this, would this maybe be what's causing it?
I thought wheel bearing because it kind of sounds like there's a howl when decelerating, probably when accelerating as well but the trucks too loud and I can't hear it. or also have heard motor mount gone bad, I've also heard ujoints but the ujoints were done this summer. the front ujoint is bad but the front driveshaft shouldn't be turning when out of 4x4 and hubs unlocked.
Corolla :: 2000 Toyota - Black Smoke When Car Is Under Load
I have a 2000 toyota corolla, with 1.8 16 valve. 105,000 miles, manual trans.. Just bought this veh. says misfire cylinder 4. So here is what I have done.
I started trouble shooting. swapping coils from cylinder 4 to other cylinders to see if the code follows after clearing it. No, stayed at 4..
So I moved on to the fuel injector. I did the same thing to see if it followed.. no stayed at cylinder 4. I changed the plugs, stilll misfire..
I did a compression check, I have 170 on 1,2,3, and on cylinder 4 I have 0. Yep, none...
I have some black smoke when the car is under load, as in acceleration, shaking and constant miss. lack of power... Trying to determine whether it is the rings or valves or what.. I took valve cover off and checked for broken spring, and they all seem ok. No oil in my coolant or vise versa.
Accent LC (2000-05) :: Missing In 3rd Gear After Driving A While Under Load
I have a 2000 hyundai accent 5 speed with 76k and a 1.5. the spark plug boots arc on all 4 plugs and can see a light blue line down the center of the wires also. But while idling you see nothing till u snap the throttle. Also driving while its under load you can really feel the miss in 3rd gear. Ok here"s what I've done I cleaned up all my grounds on motor and body ,also cleaned spark plug threads. i replaced wires with 5 different brands including factory wires and same thing. I've tried all kinds of different plugs from regular coppers to iridium and changing plug gaps with no change. the coil was replaced,crank sensor changed and does same thing.

2002 Hyundia Accent -- 1.6 DOHC 2D
When I get to 2700-2900 RPM Under load my car will chug out (basically lose power all together for a brief second) then it will come back and chug out again. I am able to max out RPM's while doing this however under load it still chugs along. WHEN not under load it rev's up fine and purr's like a kitten.
So I went and got a new motor for this car same model as was in the car before a 1.6 DOHC. However upon replacing it (also attached still was the timing belt and clutch assembly, never taken off)
So it seems to be getting spark just fine. and I replaced the MAP sensor thinking it was a intake issue however still problem exists when I am under load between 2700 - 2900 RPM it bogs out for a second losing all power.
Expedition :: 2000 AWD - Intermittent Bearing Vibration Noise Under Load
2000 Expedition AWD, 4.6l ... 150K on car, 50K on trans, 150k on transfer case and most else.
The problem is, under load, there is a intermittent bearing vibration noise...it sounds like a roller bearing that has too much tolerance so it vibrates in and out under acceleration. You can feel it in the gas pedal and chassis, you can hear it, and it robs a little power when the sound it pronounced. The sound is 10x worst when towing my 6000lb boat. Gear doesn't seem to matter, but it is hard to make it happen in 3rd gear.
Diagnostics so far:
-Can't reproduce sound on rack or out of gear
-Stethoscoped all accessories - good
-added Lucas oil additive to engine oil - no change
-added Duralube high mileage goop to trans - no change/slight change?
-Aamco said it was transfer case, tear down and inspection revealed nothing, they said it was mostly pristine for a car with 150K on it.
-Inspected U-joints - all tight
The duralube in the transmission may have made a slight difference in the frequency of the sound...but it could be my imagination, it wasn't significant enough a change to be determinate.
I think I could isolate the issue with a diagnostic tool that doesn't exist as far as I know...it would be a handheld device with 4 magnetic mic sensors you could stick in various locations and watch the waveform output on the handheld... you would simply move the mic's around until you got the highest amplitude on the readout.
At this point the only thing I can think of:
-Aamco missed something
-Main bearings, cam bearings, or possibly oil pump
-Transmission bearing (Aamco says "NOT")
