So I've been having a crazy high idle lately, and the CEL came on the other day. By crazy high, I'm talking 1700-2200 rpm...the normal is 700-900. Anyway, I got 2 DTCs back. One was a bad TPS (Low input or something), TPS replaced and the code hasnt come back since I cleared it.
But this other one I cant narrow down. P1120, Manufacturer Contl Fuel Air Metering. What exactly is this related to? My first guess is a bad/dirty MAF, or the MAF is reading a different amount of air than what's actually getting into the system (like there's a leak).
I recently installed an intake, but I'm pretty confident I've got good seals all around, and there was about a week in between the installation and the problems.
What else should I be looking at?
