k, so I definitely have an afm...it's really dirty but it's there, is there anything else that would cause my car to be running rich?

stock ecu........

B-ROB

are stock ecu's programmed to run rich??

B-ROB

I know it's really dirty...I'm gonna detail the whole engine compartment in the spring. Would the fact that it's been streetported with no major intake/exhaust mods cause it to run rich??

BigTurbo74

yes they are programmed to be rich stock, get an upgraded exhaust and things may improve a little. and please do clean that bay

B-ROB

will I have to ugrade the exhaust more than just a cat-back?? Already have one installed. I was thinking about putting an RB downpipe in, but lots of ppl say it's really loud, and not street legal. Have you had any experience with downpipes camel??



Don't worry, as soon as it gets a little warmer I am going to polich the hell out of that engine bay. It's too freakin cold to do work on the car that takes longer than an hour right now.

I dont know what your emissions requirements are but yeah, if you can get a RB header and cat back exhaust. That will really help with that streetported engine. I have a high flow cat after the RB header so my car still passes visual emissions inspection.
