Engine Performance problem
1996 Chevy Lumina 6 cyl Two Wheel Drive Automatic 176000 miles
My 1996 Chevy Lumina’s Service Engine Soon light is on.
Computer code P1406 and P0401 (Autozone)
I had the EGR Valve replaced two times in two weeks.
The mechanic’s only suggested solution was remove the intake and scrub with a wire
I also had the dealer’s service center look at the car. They suggested that a fuel additive might help clear the blockage. I’ve tried the additive and it is not working.
The car runs fine, could they be overlooking something.
