im messing with an 01 corolla. im new to scanners, i can pull codes and yada yada but i am new to the test modules, freeze frame etc.
deeper down the rabbit hole, im throwing a p0171, lean air to fuel ratio. ive replaced o2, clean maf, replaced pcv, plugs, i bought a new scanner from harbor freight, its a centech professional model, so as i dig deeper into this scanner i am finding a "fail" and cant decipher what it is that i am looking at. im guessing fuel injector #3?
can anyone shed some light?
i found this video on youtube and plan to try it out redneck engineering at its finest lol
