Re: 2008 Mazda 3- check engine light came on 2 codes
ok, so yesterday night I was driving home in the wife's car, and the check engine light came on again.
I ran the codes this morning and only got 1 code back. the same P0171, that it was running lean, bank 1 .
Same code as the last time.
So immediately I figured it's the same thing, just loose gas cap.
But this morning after I took it to autozone, I stopped to fill up the gas. After I filled up, (I put in 87 octane instead of 85 which is what my wife usually puts in it.) it wouldn't start. It would just crank. Tried several times and after several tries it fired and ran fine.
So I'm wondering,
A: why would it wait until my wife had run through almost an entire tank of gas to pop the code if it was a loose gas cap.
B: why did it all of a sudden have a hard time starting?
The possible problems the code refers to are
1-low fuel pressure
2-large vacuum leak
3-dirty/defective MAF sensor
4-engine mechanical condition
Anyone had the same or similar?
I cleared the code and will wait to see if the code comes up again.
