MAF 2002 c5 question (relays) To rich codes

[daffycats]

Looking for information ran searches on MAF I am getting a fuel to rich bank 1/2 and MAF sensor toubles. I am seeing alot of information on c4 relays and burn off relays in assoc. with MAF but have not seen anything on c5 relays. I have a procharger on the car and the dealer flashed my computer and I redownloaded the predator program and car is running rich had a test done and afr is in the 9.5 range obviously way to rich. Before I have all my computer programs rewritten and a total tune redone I had to ask the question, Do the c5`s have these relays? I asked NAPA and could not find any burn of relays listed for 2002. I have been working with procharger and they have told me the program has to still be in the diablo because the car supercharger was built and program was installed in the Predator. They tell me it could be the MAF sensor. I have checked all of the hoses and vacum lines everything nice and tight. If it had the relays I wonder if after dealer flased program and tried to start car maybe cooked relay or MAF sensor? I would greatly appriciate any help I can get. The car ran like a champion before dealer flashed computer.

Hi there,
Tip: Forget c4, as the architecture of c5 is NOTHING LIKE c4.
Second, if the dealership reflashed your PCM after you had the programming installed for the Procharger, that could be your problem.
MAF sensors are all internally powered by the PCM, so the wiring to the PCM must be checked, but I can pretty much guarantee that your reflash of the PCM is what is causing your condition.
Allthebest, c4c5
