P0171 after boost, need advice.
Hi All,
My 2003 Solara SLE Auto is recently boosted to 4psi. It was installed by Gregtrd and it ran fine with everything else bone stock + tranny cooler.
After a few days, I installed my INJEN. I got a CEL (P0171, P0174). And then I tried putting the CAI extension. Still giving me the same CEL.
I did some research, some hypothesized that it could be the AFR is leaned out because I have a thicker pipe at the MAF sensor, and the sensor doesn't know about it, therefore the Air Fuel mixture is leaned because of excessive air. I'm not sure if this was the reason, but it sounds reasonable to me.
I'm wondering if anyone has encountered the same problem, and how you solved it? I do want to utilize the INJEN and CAI.
Installed:
I have only SC at 4psi (no EBC), tranny cooler, INJEN + CAI.
I also have a Jim's fuel mod waiting for me to install.
Other Symptoms:
Before I get the CEL, if I'm at idle or a full stop, I hear sharp clicking noise from the S/C, on top of the regular noise. Once the CEL is on, it doesn't have that noise anymore.
