ran my friends work truck to auto zone yesterday, had codes for o2 sensors it has 2 of them, order on line last night, a code for a knock sensor, and p0201 witch is a cyl 1 injector, so today i had to make sure the wires had power and also pulsed, good news for him, now i need a new injector for it.
and he has a abs code, but the abs light is not on, dont get that one at all. the autozone guy turned off the scanner and lost the code, because he dont have it in his system to give to me, im like google works just fine for codes, and then said f it, not like i can fix it now.
hoping the misfire is what set off the knock sensor, or ill be changing that too if the CEL comes back on after all this stuff.
