Re: Code 18
I think a 42 is frequently caused by a bad knock sensor or wiring to it. But I'm halfway across the country from my factory service manual right now.

Re: Code 18
well i went over to his place and put a new used wire harness on it
with him and it ran fine till it gets temp. the car pops threw the intake
and stumbles kinda like a fuel or spark miss but a little worse. could a sensor be bad
replaced a cam and crank sensor with good used ones also. if i missed some thing just
let us know thanks
