2000 gt with gtp top swap. Only had the car for 2 days. Top swap with headers and CAI. Previous owner claims it was re-flashed to a stock gtp tune. Upon start up rpm's are sporadic as seen in video. If you step on the throttle it returns to a normal idle otherwise it will die if you allow the rpm's to jump. While driving power seems to be intermittent. Cruises okay but cuts out uphill or under heavier load. A few times it has jumped between 2-3k rpm until it finally dies. I cleaned the MAF sensor. I'm gonna check for vacuum leaks but does anyone have idea what the problem could be? Fuel pump? Injectors?
I posted this to a GP facebook page and someone claims its all in the tune. That i need a 2 bar map sensor and a custom tune? I have hptuners, can someone who has a successful top swap tune send me their tune?
