Been getting a P0170 code for a few months now, things seem to work, and then they don’t and the check engine light comes back on.
So far, I’ve done the following:
- replaced spark plugs and ignition coils
- cleaned ports
- replaced MAF sensors
If the car is cold, it will typically start right up no problem - and run. If it is hot - like I’ve been driving it for an hour or so, then stop for an errand and then try to turn it back on, it won’t start.
My thought is that when the O2 sensor gets hot (above 600°) it doesn’t work as well and doesn’t give power, therefore needs replacement.
However, have seen threads on here of people saying that the O2 sensor replacement doesn’t work so was wondering if folks in here have seen similar code / might know the problem. I’ve seen answers about an intake seal problem.
