Good day, i had asked some questions about this problem before and since then i have change some parts.

I have it worked on by a gmc master tech. with over 16 years experience. He diagnose it and told me that it needed a tune up and he did it. parts change (5 new coil pack, 8 ac delco spark plug and wires). He flush the fuel system and take out the injectors and check them for the right psi.

Over $1,000 dollars later and the problem still exist.
The hesitation is not as much but it still happen. One minute it will fight to pick up speed then the next it drives fine.

ANY Suggestion?

The heat does not come out of the dash vents at all. Works good in the floor and window vents. Could it be a vaccum problem. Would like diagram of actuater door location, and hopefully how to narrow down the location. Thanks for your time. FRANK
This has happened 3 times in the past few months. The first time - it stalled when I put it in park in the driveway after driving it to and from and appt.
The second time - it stalled while I was driving it slowly in a parking lot.
The third time - it wouldn't start again right away shortly after I parked the car.
Each time - I let the car sit for around 30 minutes and it started right up again.
Mechanics ran diagnostic on it, and tested fuel pressure, and both came out fine.
my truck runs fine, its when im stopped for certain periods that my transmission sounds like its shaking and the rpm guage varries from 500 to 1200 rpms. and if im parked for long enough the enguine sounds like its trying to shut off. this doesnt happene every time but it happens enough for major concern.

Hi
cant believe the amount of vibration while you are riding or idling in this car. Mechanic said that is just how they are. Even my 12 year old complained. Are all Honda 4 cylinders of this year and make like that?
