Running to rich, what mods do you have?

If you have an AFC then lean it out, if you don't, then get an AFC and lean it out.

If you're car is stock, then it sounds like your ECU is sending your motor to much fuel. Might have to get it replaced.

Jeez, nice answer Robin :roll:

If it's running too rich, you can always remove your honeycombs or back the screw out on your MAF

2G!!!

DO NOT REMOVE ANY HONEYCOMBS.  THIS WILL MASSIVELY FUCK THINGS UP.  HONEYCOMB REMOVAL IS ONLY FOR 1G.


Though Jovan'd be right if you had a 1G, Dennis.

No, you just can't remove the honeycomb from the center section.  Bottom is fine, I wouldn't touch the side ones, and definately do not touch the center section.

He's not a 1g?  Meh, doesn't matter, you can still remove the lower one and not the side or top ones as Kimyee pointed out.  Either way, backing out the screw should do the trick as well.  Graeme, I strongly recommend decaf from now on.

it could be alot of things such as O2 sensors, maf sensors, fuel pressure regulator, tps, etc.... i would take it to a dealer and get them to check it on a osiloscope (spelling) to pin-point the actual cause, rather that trying to compensate for it.
