I installed BMS intake about a week ago; drove around, SES came on, went into limp mode. Turned off and turned back on...ran fine
Yesterday it came back on (light, no limp mode)
I cycled starting it a few times and nothing so went to have it read. P-Code is P2177--system to lean off idle speed bank 1
I searched and couldn't find the code on here. Any thoughts on where to start? Not sure if that's referencing a vac line somewhere or the maf sensor? I assume its something I did bc it ran fine before.
