Rough Idle- Engine Light P1074 P1071 Codes
Am trying to narrow down an issue with rough idling. I have checked for vacuum leaks, and just got done cleaning the MAF.
Error codes tell me lean mixture, etc, etc.
I just had the fuel pump replaced less then a year ago. And the fuel filter gets replaced every other year. (it was replaced last year.)
Runs good, just is getting worse now with idling.
Any recommendations? MAF? H2O2 sensors?
This has me stumped, and I am new to this. I just don't suspect a fuel pressure issue.
Car has 135K miles on it.
Thanks
