code 0171

well my 09 threw this code and the guys at autozone printed out a sheet saying that 1. oxygen sensor defective 2. ignition misfire-repair 3. fuel injector problem.
this happened once before after i put my sri on and i found that a couple of the clamps worked their way loose. so after i got back from retardzone i popped the hood and checked the clamps and yep the one on the tb was loose so i tightened it. anyone have any thoughts?

when i put on my sri it backfired and the engine light came on, after disconnecting the battery and reseting the ecu, the problem went away for me, though i never knew what the codes were

hey mine sounds like it backfires when i turn the car off. but im going to keep an eye on those clamps this week and c how it goes.

that is wierd as hell, idk lol
