I went to autozone today to test my car out after adding a new coil from the scrap yard due to a misfire that still occurs these are the codes what will i have to replace? any suggestions?
171= system to lean bank 1 (exaust rear bank 1 used just replaced)
401= exaust recirculation flow insufficient detected (egr all air pipes recently cleaned)
306= cylinder 5 misfire detected ( coil just replaced)
Is it time for a timing chain mod if so what are some racing timing chains and where can i get them? Or could i get something like a lsd or diablo chip to retard the timing any suggestions on what to do or where to get cheap parts will be appreciated
