Yikes, it could be the clutch?
I've been having a similar problem for quite some time. Always worsens after I've been driving for a while. However, some days it does it as soon as I start it up, or not at all if I'm just driving around town.
If I turn the car off and on again it will go away, but eventually come back.
I have talked to numerous people about this and have had conjectures of anything from a dirty MAF, to a vacuum leak. Some people had told me it could be the boost solenoid. I was thinking it could be the TPS.
It's nerve wracking when it happens, because it seems like the car is dying. It's frustrating, because I have had this issue for over a year and have not been able to pin point the issue.
Sorry to reopen this clearly old thread, but I'd really like to get as close to an expert opinion as possible. So if there are any professional mechanics on here. Please give me your input I will be extremely grateful.
Everyone, please don't post opinions or guesses. I know it's hard to diagnose without the car in front of you, but this sort of issue obviously has affected other people's cars.
If you have had this problem, or one similar how did you fix it?
