I just bought an 85 iroc with a 350 tpi and it drove home fine but then today I washed it and now it runs like crap and idles really low and it like chokes when i try to rev it. I'm getting codes 24, 32, and 33 from the ecm. Any help would be great!!!

 

has the car sat for many years? if so your sensors may of went bad once it got to temp but i dont think that many sensors would go bad like that more likely the ecm may just be bad

 

Well does anyone know what those codes are? And the guy said that it had been sitting for a couple months but that all really... What sensors do you think need replaced? Like MAF and oxygen? Or what? One more thing, the fuel guage is stuck at like 5/4ths all the way past full anyone have any ideas? Thanks!!!!

 

here there is a whole guide here

fuel gauge is probably the float in the tank or gauge in dash is screwed up somehow
