Engine Performance problem
1989 Chevy Celebrity 6 cyl Front Wheel Drive Automatic 149544 miles
I have an 89 Celebrity with the 2.8 and 149 on the clock. One day the car ran perfect, the next day, it ran like garbage. At idle, it misfires and upon acceleration it has a slight backfire that I hear coming from the cat area. It also misses like crazy upon alcceleration. At idle, you can hear the misfire through the exhaust in the form of a put. Put.
Another weird thing is when I am at a cruising speed with light pedal pressure, it misfires like mad!
I changed the plugs, used 3M injector cleaner in the tank but no luck. I also checked the wires for an arc but everything looks good.
Does this sound like a bad injector?
have the same problem?
