Engine Performance problem
1998 Chevy Tahoe V8 Four Wheel Drive Automatic 14,000 miles
my 98 Tahoe 2-door had a new engine installed but the mechanic put the EGR valve in upside down. It was driven for 12,000 miles before I discovered the problem. Now the engine misses when I decelerate from 75 going down hill and hesitates when I feather the gas. It clears up again at about 60. The check engine lite flashes. If I accellerate hard the lite stops flashing. What.S wrong? Could the cats have gone bad? Help please?
have the same problem?
