I need help. In have a 1999 Cobra and all the mods are in sig. I have recently had the car tunned and leaned out the fuel a little. A few weeks later my car started hitching and popping and not having any power around
2k rpm...Threw a code P1151... After that i changed the o2's but it didnt work, then i clean the MAF and that has seemed to stop the hitching and popping, but the car agian threw the same code...what should i try next?
