CEL on, P0171 code. I've tested the O2 sensor, fuel injectors, coolant temperature sensor, MAF sensor (cleaned as well), changed spark plugs (unrelated but was gonna do it anyway). Checked and reset the ECM. All working fine. Picking up a PCV valve tomorrow hoping that works. If it doesn't it looks like I'm going to have to take it in for $85 diagnostic...anyone know what else to try? It all started after having to change 2 fuel injector o-rings. It runs fine, no problems starting, no high/low idle....um...help?
