I have had an idle issue for awhile where my RPMs at idle will drop down to 500 as if the car is about to stall out. Included with this is usually a CEL, P0174 (bank 2 too lean) after the RPMs drop a few times.
I have gone through and cleaned the MAFs, looked over for any intake leaks but have not found any. Need to get the bumper off and possibly check by the intercooler area. I went out today and logged the car with everything I could with Cipher and got the RPMs to drop. Attached a file, but you can see at 38 seconds the car freaks out and the RPMs just fall. If anyone can take a look and has some insight into this matter.
