So i bought a grand prix gt that has a top swap kit on it about 6 months ago. Its a 2001 has headers 1.9 rockers CAI 104s and 180*. I havent had any problems with it until these last few days. When i first start it the ltft will go up to 16.4 but after moving the car it will drop to 10 something once cruising itll go from -16-11 sometimes maxing out both ways -22 or 16.4. WOT it stays at zero. 0kr except occasionally .5kr max maybe but WOT through 1-2 none. The car also has misfires about 10 on average at idle if i hold the revs up it will keep climbing in misses. Ive heard bad things about running that lean and its making me really nervous to drive the car anymore.
