Toyota - Camry :: 1992 - Stalling When Come To A Stop And Taking Foot Off The Accelerator
I have a '92 toyota camry that we just purchased and put a new engine in... now it's stalling when you come to a stop and are taking your foot off the accelerator. we've tried a fuel injector, a fuel clean, fixed vacuum leaks, and replaced the fuel filter, and fuel preside regulator... it's still doing it and is getting worse.

I have a 1994 gmc sierra 4x4 5.7 with a rebuilt engine 2 yrs ago and it has started having a rough idle(surging/dies) I have replaced fuel pump, fuel filter, maf sensor, iac sensor, tps sensor, top half of the tb and injectors, distributor, ignition module, plugs and plug wires and still no change. Yesterday I cleaned the iac and seemed to straighten up a little but then got in it to go to work today and it was back to running rough again and seemed worse. I am at a loss.

The engine continues to rev after I take my foot off the accelerator. Does it under many different conditions, but especially the engine needs to be warmed up for it to do this. Toyota just called to say there is nothing wrong with it, even though I had a technician drive it and tell me "this is messed up!" Apparently the master technician that worked on it today didn't have a clue. Under warranty and will fight it! What is wrong with the car?

My wife's 06 expedition 5.43v runs rough loud and dies. Not all the time just when it's to hot. I got a code it's p0022 cam sensor. I changed both started the rig up and heard loud rattling like metal maybe chain. It lasted for a the length of my video 1.4mins give or take then went fine, i turned the car off and back on everything seems fine. I know I got her oil done after driving. She had metal/plastic in her oil. I had all plugs done and actually i re did the 8th cylinder plug because it was miss firing and i pulled it by hand with only the socket no ratchet. I'm thinking the chain is going bad if not already bad. Only 113k miles my 04 f150 5.43v lasted 250k before motor swap...

I have a 99 f-250 with about 250k miles. Truck is completely stock. It recently has developed a problem where when I start it in the mornings it surges at idle, 200 rpm or so. Sometimes it tries to die and did once but started back up. When driving it continues to rev itself up and is jerky. It runs rough and sounds like it could be missing on a cylinder. At other times it runs fine just like normal. Yesterday morning it started with these symptoms so I put in a new ford CPS. It ran great for about 100 miles that afternoon. This morning it started back with the same symptoms. The SES light stayed on longer than normal when I started it, but it went off. I don't have a scanner.
I thought it might be water in the fuel because this started the day after I filled it from my transfer tank. But the water in fuel light has never came on. I put a new fuel filter on it but it made no difference. Have pulled filter three times looking for water but never found a drop. Also pulled several buckets from the bottom of my transfer tank but found no water there either. Where to look next?
Prius (2004-09) :: Noticeable Deceleration When Take Foot Off Of The Accelerator
It seems to me my Prius 2007 decelerates noticeably when I take my foot off the accelerator. It's noticeable but not even near the level of the engine braking in B mode. The change seems to have happened since my last service but the I won't swear to it, and the dealer says there hasn't been a software change.

My sister's 1991 Volvo 240 automatic. She is scared to drive it. When we push the accelerator fully down while in park the car makes a sound of accelerating hard and decelerating, it occasionally makes the sound of a backfire. All the sounds are coming from under the hood. When in drive it will not actually accelerate past first gear, it will buck back and forth, and still makes the sounds. Its almost like a shutter. Reverse is the same. We recorded the sounds.
View 3 RepliesMazda :: 2007 - Sluggish Acceleration / Stops When Foot Is Off Accelerator
I have a 2007 Mazda 5 and over the past few days, I notice the acceleration seems slightly sluggish, especially on inclines. Then last night I had a problem where I was driving and whenever I took my foot off the accelerator, the car would stop (rather than gradually slowing). And when I put my foot back on the accelerator, the car jerked forward before finding the right speed. I parked and after work, it drove just fine. Drove fine this morning also. The shop says I need a new solenoid purge valve, but after reading about that valve, I don't understand how it could cause my problem. The car didn't stall whom it stopped, it just stopped moving forward.
View 4 RepliesToyota - Highlander :: 2009 - Pop Coming From Rear When Take Foot Off The Accelerator
Ever since I got a brake job, my brake lights have come on, all 8 of them. Traction Control, ABS, Brake, etc. Every once in a while they will go off and be normal for a day or two then they will come back on. The service center that did the brake job said everything looks good, it must be a faulty brake actuator.
The brakes work fine although on starting I have to remove my foor from the petal and then reapply it to move the transmission from park to drive. When on the highway doing 70 mph or so, when I take my foot off the accelerator I hear a pop coming from under the rear of the car mostly on the passenger side. In about 5 minutes, I'll hear it again. It sounds like pressure is being built up than all of a sudden released with a pop.
Actuator replacement and I rather not go through the expense if it is air in the brake line of a faulty sensor.
Ford Super Duty (1999-2016) :: Scary Clunk In Drivetrain When Take Foot Off The Accelerator
I have a 2001 F250 7.3 with 175K.
Here is the situation. There is a disturbing clunk when I take my foot off the accelerator and a corresponding clunk when I push back down on the accelerator. This only occurs when the vehicle is not under load. That is, it does not happen when going up hill or on any sort of an incline. It does not happen when the automatic transmission shifts. It does not happen shifting into reverse or drive.
It does not happen when starting or stopping. It only happens when I am at 40-60, or so, miles an hour and let off the accelerator and/or press the accelerator again. It appears that I can carefully feather the accelerator to eliminate or, at least, minimize the clunk. I have crawled under the truck and it looks like all the U-joints are tight, I have lubricated the slip-yoke (although when twisted there is, like a mm of play when this is twisted, not much but a very little).
The rear-differential pinion appears to be tight (no side-to-side play or up-and-down play, or at least I can't make it move with my hands). However, when the truck is in neutral the entire driveshaft is able to rotate a half inch, or so, all the way up and down the drive train. That is, the transfer case and the rear differential appear to have a little rotational play in them, but I am guessing this is pretty normal. When in park the entire driveline seems solid.
I have seen from some of the other posts that this sort of clunking can come from leaf springs, hangers and such but since this clunk seems so isolated to acceleration changes when the vehicle is not under load, I doesn't seem like this would be the issue. No clunk when shifting, turning, bumps etc. Everything seems perfect until I am on a gentle downhill or flat and let off the accelerator. Doesn't appear to clunk when going down a steeper decline. All this gets me to thinking that the clunk is caused whenever the driveshaft rotation gets ahead of or behind the rotation in the rear differential.
Ford Excursion :: Louder Roar Coming From Rear End When Taking Foot Off The Accelerator Without Pressing Brake
After putting my front end back together except new springs, new shocks, and new track bar, just to give everyone a little history of what I've done to it. I've had it for 8 months and maybe put 1000 miles if that because of working out of town a lot and the front end torn apart. I've noticed a louder roar coming from the rear end when taking my foot off the accelerator without pressing the brake. It feels like the tow button is engaged, but isnt. I have no issues with handling besides knowing it still needs alignment. I'm taking it to the dealership tomorrow for a 4 wheel alignment. It sounds and feels like I'm riding on mud terrain tires.

I have a 2005 325xi BMW with 31,000 miles I get regular oil changes. Recently the engine seems to be running a little rough. The other day, after driving about 15 miles, the car started shaking and getting progressively worse. At first it seemed like the tires, but later it seemed like the engine. Also, when I accelerate, it seemed to get more rough, but again, not all the time. Last night, it was the worse yet. After I left the car for 2 hours, it didn't happen right away. Then it did again, but with 2 more miles to go til home, it stopped! Not sure if it's the fuel pump, fuel filter or even something with the wheels (sway bar?)?

View 2 RepliesPrius (2004-09) :: 2005 - Engine Running Very Rough And CEL Flashing
We have a 2005 Prius with 77,400 miles on it. My wife came home from a short trip yesterday saying the engine was shaking the car and the CEL was flashing. About 4 months ago we also had the CEL come on but not flash and it ran a bit rough but not as bad as it is now. I was told by our local dealer that a flashing light is worse than if the light comes on and stays on. When this happened 4 months ago at 74,000 miles the dealer said they downloaded codes P300, 303, and 304 and that I needed to replace all 4 fuel injectors.
I realize that 300 is a general misfire code and 303 is a misfire code for cylinder 3 and 304 is for cylinder 4. After reading some advice on here 4 months ago, I cleaned my MAF sensor, ran some fuel injector cleaner through a tank of fuel, replaced all 4 spark plugs, and started buying Chevron gas. The CEL stayed off and our mileage went back to normal. I thought I had solved the problem but now this after 3000+ miles. I checked all the ingitors, connections, spark plugs, and wires yesterday and all seem to be in good condition. Maybe they were right and the fuel injectors are going bad. I am at a loss as what else to do other than take it back to the dealer now and plan do that this afternoon.
Ford Escape / Hybrid :: 2005 V4 Will Not Start / Running Rough
So my wife's 2005 escape currently will not start. It was running rough so we brought it in to the shop to have the codes read. There was a bad MAF sensor code so we brought it home and were gonna replace the part the next day. The next day rolls around and it refuses to start. Swapped out the spark plugs which was much needed, replaced the valve cover gasket, which had also gone bad, and put in a new MAF sensor. It still refuses to start. It will turn over, but never starts. Also, the sound as it turns over doesn't sound right. It's hard to explain what sounds off about it, it almost has a "soft" sound to it. I can try to explain better if needed.

I have a 2005 Camry and it was stalling while driving occasionally. It had gotten worse, so I cleaned the throttle body as was suggested. Now, when I try to start it, the engine revs really high then goes back down and dies. This is without putting any pressure on the accelerator. What to do next?
View 1 RepliesCamry :: 2002 V6 LE 1MZ-FE - Rough Running At All Speeds
I have 144,000 miles on my V6. Just started to notice that the car is surging/hesitating at just about all speeds. It appears to idle fine and if you raise the RPM in neutral I can't detect a problem. If you place the trans in drive, apply the brake and raise the RPM to 1000 to 1500 the engine's RPM varies slightly and regularly, it not steady like all of my other cars. When you are at highway speeds you can feel the car slightly buck, if you take it out of overdrive it is more detectable due to higher RPM. I do not notice the problem when the engine is cold.
I have a hand-held scanner and I see no codes and there is no CEL illuminated. I changed the plugs with OEM plugs at 90,000 miles when I changed the timing belt. Changed the air filter probably 10,000 miles ago. Just cleaned the MAF sensor (after the problem started), no change. Took it to the dealer. They discovered broken motor mounts which I kind of suspected I had, but I didn't feel the symptom were mount related. They said that I was feeling torque converter lock-up. I told them that the range of speeds and gears that the problem presented itself that it was unlikely lock-up.
Alldata suggests that it is a fuel problem and Toyota has some TSB's for drivability. I'm discounting the TSB's because this just started recently. Any hints as to where to try first? EGR, fuel regulator, fuel pulsation damper, injectors, spark plug coil packs, ..... It gets too expensive to just remove and replace the sensors that deal with the fuels system. I have plenty of tools plus a volt-ohm meter and a fuel pressure gauge.
07/21/2009 : While I was at work I added Seafoam to the gas, tank was half full.
On my way home from work I disconnected the EGR Position Sensor connector and the symptoms disappeared and the expected CEL illuminated. When I arrived home I went on Alldata and looked for an EGR system test. I found two, one for the position sensor and one for the EGR temperature sensor.
I had to run out to Sears to pickup a vacuum pump. I performed the tests below up to the point that I needed the pump. I also removed, inspected and reinstalled the EGR Position Sensor before I left for Sears. I did not notice the symptoms on the trip about 14 miles round trip. I'll see if I still have the problem on my way to work tomorrow.
Performed the on-vehicle inspection as listed on Alldata
EGR Position Sensor resistance: 2.6 ohms, in spec
EGR Position Sensor power: 5.0v, in spec
EGR Position Sensor output with no vacuum applied: 1.0v, in spec
EGR Position Sensor output with 5.1 in Hg vacuum applied: 4.0v, in spec
07/22/2009 : Problem seems to have gone away, no bucking or hesitation. Maybe the connector contacts were dirty on the position sensor. Will update if the symptoms return.
09/07/2009 : Noticed that I am getting 2 miles per gallon more than before I found the problem.
