So I'm throwing some codes after Chevy installed my exhaust. P0036, P0133, P0141 02's and crank sensor I believe but when I bought the car at dealer he said had to replace crank sensor to get car running when he got it from auction. I just had Chevy install the mid length header and down pipe a month or so ago and the lights were on shortly after just finally got around to posting about it though. My car has gone into limp mode once for me when I smoked the tires pulling into my parking lot at work, were i unhooked the battery and it fixed it. And one other time for my old lady who basically did the same thing pulling out of work about 3 months apart. Those were the only times for that so maybe a stored code from when she did it because I never reset or cleared it..... Any advice should I clear eM and see if it goes away or just say f it and buy the 02s. Also sorry for massive post I get a misfire till car warms up brand new plugs its stage 2 and I believe I gapped em at 35 or 37..... I wanted to upgrades coils but zzp not in stock anyone know who else sells them.... And zzp what's up with all these parts not available. Coils intercooler etc.....
