Once again i am having drama with my GP. I need some advice/ insight on what could be my problem.
I have NIC cam, i recently had it tuned but it still is not running correct. When i start the car i have to pump the gas like an old carbed car. Once its running it runs real rough for the first 10 seconds then seems to settle out. If i leave it running or tap the gas it will start to surge on its own, drops to 500 RPM and climb back to 1200 RPM. If i start driving it hesitates when i try to accelerate, sometimes it stalls. After crusing from 60 or so and come to a stop light the RPM will drop down and start to surge again just like above, stalls most of the time once the car stops. When in gear it always hesitates when trying to accelerate, bogs down then picks itself up.
The other week i was trying to drive it and i had a p102 code pop, i checked the MAF and cleared it. The code has not came back up.
As for the tune, i have read that the NIC cam needs to be in OL but when i was looking at the tune that i had someone due, its set for CL, the enabled degree is at 44. If it is suppose to be in CL it should be 255 or higher, correct?
My question is do you guys think this is a tune issue or a mechanical issue?
If its mechanical what ideas do you guys have?
I have checked the MAF, replaced IAC and checked all vac lines.
Thank you for your adivce, sorry for being so long.
