IS F (2008-2014) :: Engine Cut Off On Drive When Accelerating Hardly
Jun 8, 2015
I bought a 08 isf a week ago and its not in a really good condition it has done 177k miles and its moded with a k &N air intake and nameless exhaust.. According to its performance it still feels like 5.0 v8 and it gets to 60 less than five.. However the engine automatically cut-offs during a full throttle on 2nd and 3rd gear (during drive) so i was wondering if this thing is normal or the previous owners have done some tuning to its ECU.

Well I am not sure if i have trans problem or not. If I put the trans in drive and go through the gears when the RPM's get to about 2000 the truck almost stops accelerating, until you give it much more gas, this happens in every gear. but If you push the button to take it out of overdrive and drive like that it doesn't do it.

My friend just bought his ISF two weeks ago. It's bolts-on. He has an issue...
While hard accelerating in all modes the car some times shifts @5500 RPM...
What the problem is?

I just got my ISF 3 weeks ago and this issue got me pretty worried. I would like to hear if there has been a recall or a fix on this issue. While in Drive (D), the tranny wouldn't shift past 2nd for a couple of seconds. It went as high as 4.5RMP and wouldn't shift, the RPM kept going up. Letting go off the gas did not work, the RMP just stood where it was and slowly decreased with the speed. This lasted for a few seconds. I must admit that I was just pulling out of the driveway and she wasn't properly warmed up (16 degrees temp or 60fh)...

Just a note to mention that last Friday my fiance was driving her'13 F150 with Ecoboost (73,000 mi) and heard a "loud" pop when accelerating then engine lost power. She called me so I had her restart it and all seemed fine- but drove 1/2 mile and same thing. Called Ford roadside service- got a tow within 30 min to dealer down road.
Turns out they had to replace the throttle body. Fortunately I have the Ford Extended Warranty thru 125,000. This was the second significant failure for the truck- first was a leaking A/C Evaporator which required pulling the entire dash. I won't keep this truck beyond the extended warranty.

I have a 2008 Prius and recently hit the 85K mark. A couple of weeks ago, about a week after my most recent oil change, I started noticing a noise when I accelerate. It's kind of a wah-wah-wah-wah or wuh-wuh-wuh-wuh noise that gets faster the faster I'm going. It's not terribly loud - I can't hear it if the windows are open or if the volume on my radio is cranked up.
It disappears when I stop accelerating or sharply reduce my acceleration. At about 40-50 mph, the noise goes away. I'm not sure if this is because road noise blocks it out, or it's so fast-paced that it just becomes one constant noise.
Today for the first time since this all started, I also noticed that unless I'm not accelerating at all, I have poor gas mileage (like under 25 mpg). This happened once before and went away the next day so it might be unrelated.
Can I wait until my 90K service to have this checked out? Should I visit my mechanic now? Do you think this is a timing chain issue? What am I looking at?

Today I parked my 2014 Toyota Corolla while the shift was in drive and I turned off my engine. I let go of the brakes and it began to move backwards. I then realized what happened and shifted to Park and took out the keys and turned the engine back on to park it correctly. The on screen display seemed to restart or something when I did so. Will this hurt my vehicle? It is a CVT transmission by the way.

My 2008 F150 rattles (from engine area) when I let off gas while in traffic or in a drive-through. It almost feels as though it's going to stall. Drive thru, parking lot, traffic are all examples. "Stop and go" push the gas to move forward and quickly let off gas. I let off the gas there is a large rattle coming from my engine. Not sure if it's miss-firing or if it's an exhaust leak or a timing chain issue. I'm having trouble trying to figure this out because it does not happen all the time and have been unable to re-create when I go to the mechanic.

Since we purchased the car we've been having problems with the transmission or acceleration, when the car is shifting from park to drive engine speed RPM goes up and it is difficult to stop the car from driving. The dealer does not know what to do and the factory support is useless.

My truck is a 2004 (new body style) 4.6L XL Supercab 4x4, trans code A, which I believe is the 4R75W transmission. I bought the truck used last year with 110k miles on it and it still only has 115k now. I think the problem with the trans was there when I bought it (it's highly intermittent) which may be the reason why the PO traded it in, because the truck is in excellent shape and has clearly been well cared for in all other regards.
The problem only occurs after having let up off the accelerator pedal for a while and coasting, then getting back on the gas without coming to a complete stop, like one might do coasting downhill or coming up to a light that turns green before you come to a stop. When that happens it feels like the transmission has shifted into neutral and the engine revs up freely for a second or two and then suddenly engages and clunks / slams into drive. This doesn't happen every time that I attempt to reproduce it, and it went for the entire summer without doing it once. But, now that winter is coming on in New England I find that it is doing it again once in a while. The problem seems to happen whether overdrive is engaged or not.
I've checked fluid level and condition and both are fine. Nice bright red color and no burnt smell. The transmission works well in all other ways except for this one issue. With the exception of this problem it seems to be engaging, driving and shifting perfectly, with no slipping, even when giving it a good romp, with or without 4x4 engaged, or even carrying a heavy load, causes no problems.
To me, this seems like a control problem of some kind, doesn't it? If it was mechanical or hydraulic I wouldn't expect it to only occur after coasting for a while.

I have only had my 08 F for a few months and it is due for an oil change in about 1K. Today the low engine oil light came on, so I checked it and indeed it was just below the low level on the dipstick. The light came on once before while I was parked on an extreme grade, and the oil level was fine. I have no evidence of any leaks. This doesn't seem as though it would be normal. By the way it took about 1/2 qt to bring it back to normal levels.

About a week and a half ago I took my 2008 ISF to Lexus to have them check out the ticking noise. My car has 63K miles on it and I notice the ticking noise after it is fully warmed up. I normally have just been driving it in Sport-Manual too. The sound seems to come from the driver's side fender well area and I hear it best when it is in drive in my garage or at a drive thru.
At first Lexus couldn't duplicate the sound even after driving the car. So I went to the dealership and drove the car about 10 mins for them to hear. The service advisor and a technician heard it this time. They had to call the regional Field Technical Service rep for direction on how to proceed. The FTS person recommend swapping the driver's side high pressure fuel pump to the passenger side to see if the noise followed the pump. I guess they've had problems in the past with the high pressure pumps on the LS models. I again went down to the dealer to drive the car and the noise stayed on the driver's side.

So earlier today i noticed this unusual noise coming from the engine bay. You cannot hear it if your sitting inside the car. Only time you can hear it is if the car is running and you happen to be standing in front of the car.
The noise isn't constant and tends to come and go. After about 6 plus tries trying to film it, I finally got a clip where you can hear it for a bit.

So I changed my oil today and added about 9.8 - 9.9 quarts. There was just a little left in the second 5 quart jug. I carefully added some oil while checking the dip stick frequently. I made sure the level was just at (maybe a hair above) the top dot on the dip stick. After that, I went out for a spirited drive.
Now 4 hours later, when the car is relatively cool, I checked the level again. However, the level is now significantly higher than before. It's definitely past the top dot, not by a lot, but definitely more than before.

Owning a Lexus . I recently bought an '06 model GS300 and have just had an issue appear with it.
Issue is that, whether in drive or reverse, the car accelerates on its own - not very quickly, but quickly enough that it'll crash me into my garage door if I'm not careful.
What this could be? Variously, I've read that it could be a Throttle Positioning Sensor, or Idle Air Control valve. Some things I've read suggest it could be air conditioning related (though I don't understand that one...).

So I drive a 2003 VW Touareg....and the other day while driving, felt this strange vibration when accelerating over 10mph. The dealership said it was an $1800 repair and diagnosed it as the drive shaft.

I have a 95 Olds Ciera 3.1L Auto Transmission 150,000 Miles. While going down the highway as I was accelerating the transmission went out of gear while still in Drive (felt like I was in neutral and coasting). I found that the only gears that work are 1st & 2nd No Drive or Reverse. This happened suddenly without any hint of a problem prior to this. when I got home I checked the fluid (which I changed last summer) It was still clean and did not have any unusual odor, also the fluid level was fine.

I noticed my sound a few weeks ago but wasn't as loud as the videos I've seen. Didn't really bother me. I did notice today that the sound was a lot louder . The only thing that has changed is i had my oil changed over the weekend with mobil 1 5w-30 fully synthetic. Now I don't know if that could factor into the sound getting louder.
I am really hoping its just a cat and i can replace my headers and everything is good. i just got the car with 19k miles on it and do not have a warranty.
I have been worrying about "engine noises" for years and at this point if its something i can't fix without dumping thousands of dollars into it, then so be it. I am just going to enjoy the car too the fullest. Plus, once i get full exhaust, it will work with canceling out the ticking sound.

I have an issue with a 1993 Ford Tempo. It is owned by a auto parts store and is used for deliveries so it gets a lot of use from day to day. Several different mechanics have looked at it and no one can figure out exactly whats wrong.
The issue is this - The car stalls out at about 2 or 3 oclock everyday after being used for deliveries starting at 9 oclock. It will stall while idling in park, while stopped in drive, while coasting/accelerating in drive. The temperature is normal. Is will start to idle and run very rough and the car is less responsive to the gas pedal about 10 minutes before it stalls.
Once it stalls, if it is allowed to sit for about half an hour it will start and run fine for a little longer but eventually stall again. After it sits for a few hours it is fine to run for a few hours again. If you try to start it right after it stalls the first time the engine will turn over but stall out again in a few seconds, if you keep trying to restart it it will eventually not even crank. Also it will occasionally stall like this/run rough in the first 10-20 minutes of driving.
