Throwing codes (2002 SS)
Throwing codes (2002 SS) I've been throwing these same codes for awhile now and I've been trying everything to keep them from coming back. Here are the codes:
P0171 Bank 1, Lean.
P0174 Bank 2, Lean.
I've been working on finding the problem for awhile. Here is what I've done to try and solve this problem.
1) Replaced the Air Intake seals.
2) New MAF. (Granetelli w/Cold Air Tune)
3) New K&N air filter.
4) BBK 80MM Throttle Body.
I can't think of anything else that may be causing the lean air fuel ratio. Just some more info on the car so maybe someone can figure ths out. I drive it in southern california and I run premium fuel and always have. I've been trying to get a tune, but having trouble finding the time off. Do you guys think that a tune can get rid of this problem?

I changed the filter about 3 months ago when it first started. No luck. I've sprayed carb cleaner along the whole intake and tb and no change in idle speed. I'm getting a hiss, but I'm not sure if it's coming from the belt or from the intake.
I checked it out and not tears or cracks. When I re-installed the throttle body and I made sure to tighten those hex screws up nice and tight. I noticed something that I hadn't noticed the first time I installed the Throttle body. The spacer on the BBK (Stock has no spacer) was causing the smooth bellows to push the MAF to far into the Lid. So the lid was latched, but it was being pushed from where it use to sit. So I cut the smooth bellows to allow room for the space that the TB spacer took up. I drove it around the block a few times and no SES light (Usually it pops up within 2-3 miles after I clear the codes). I'm really hoping this is going to solve my problem, but only time will tell. Thanks Craig for your help.
