I've posted and read many great questions and answers for the all too common codes for the f-body's. 34,36,45, etc. I have all of these codes and done some basic testing on these but no cure yet. my question is wich code to tackle first? I fear that the route code is causing all the others. like i have a code 45 which is o2 rich code and this could be throwing the maf and maf burnoff codes. like everyone else i will try to avoid the largly over priced maf sensor replacement if possible LOL. its a 88 305 tpi iroc, its a toy and sits alot. i want to get this horse running right so i can drive it instaed of look at it. SYMTOMS,runs rough, idle irratic (mostly cold but even when warm), runs way too rich (black smoke) engine light on (obviosly). What do you guys think?

 

i would check your o2 sensors first. if i remember correct these have the single wire type if those go bad it would make your car run eye burning rich.
also LIGHTLY tap your maf sensor while it is running. If your car stalls then you found your problem.
good luck
Almost forgot do you run a K&N type filter? if so you might need to clean your maf it could be oiled over

 

i did do the maf sensor thing and unplugging. i will replace the o2 soon anyway. its the origional. we'll see what happens from there thanks and keep the tips coming.

 

looks to me like you got a burn off realy problem, how good are you with wiring, checking voltage etc.?
