Engine Performance problem
1998 Chevy Suburban V8 Four Wheel Drive Automatic 155610 miles
I have 1998 Suburban that is missfiring.
We have replaced the intakemanifold gaskets, and that started to take care of the problem. I have also installed a JET Mass air flow sensor. When I put in the sensor I started to get bank one, bank two rich codes, and random missfire codes, when the check engine light came on.
The truck tends to sputter/missfire more in the morning until it get going, also if I hold the pedal constant and start to go up a hill it will sputter.
Just wondering if anyone had any insite.
have the same problem?
