I got my Flowmaster system installed about 2 weeks ago, and yesterday my check engine light came on. It also almost died this morning while it was idling. I took it to AutoZone and they checked the OBDII trouble codes. I got a P0171 and P0174. They cleared those codes for me, and the light went off. Now, the light came back on and it went back to "safety mode" (reduced power/acceleration, etc).
Any idea what the issue is here? Thanks!
