Possible PCM issue? Updated with New issue and Link!!
Car: 2000 Camaro SS
4 days ago after getting gas and letting the car sit for the time i was in the gym (1-1 1/2hrs) i proceeded home when i didnt even got a block and the car started to buck and felt like i had no gas. I got out and fiddled with the gas cap which felt loose and everything was fine. Flash to yesterday, trip to gym no problems, come back out start the car and was having a conversation when the tone of my ca changed and i could hear it running terrible. Exhaust not was choppy and sounded like it was backfireing, also felt as if air was being sucked into the tailpipes and not firing out of them, then the check engine light started to flash. Played with the gas cap a little bit and was able to get home but the car wasnt running right. ANY SUGGESTION!!
Key Points- about 2 months ago I installed LT headers, removed my cats (ORY) and removed all my emissions (AIR,EGR). I have not gotten my PCM retuned for that so my check enhine light has been on anyway. once this happened i immediatly thought of my computer and ordered a tune from PCMforless calibrated for my upgrades. Please Help! My poor baby!
