hey i just put in a new tranny, clutch, cat-less midpipe and mil eliminators. anyways i have a ridiculous exhuast leak and my light is on. it threw 3 codes, P0174, P1000, P1266, and i know what the first two are but does anyone know what P1266 is? its not listed in the book i have... if anyone can help that would be great. hopefully a few drive cycles will cure all...?

 

P1266 is a High to low side short. Every time I've seen it's been a bad injector.

 

where is your exhaust leaking from?

 

i might have a bad injector cause i have a crazy sperratic idle that i cant trace... thanks for the info though... i think im leaking from bank 2 right after the header
