Engine Performance problem
1989 Buick Regal 6 cyl Two Wheel Drive Automatic 129000 miles
My 89 Regal started to run poorly and eventually quit and wouldn't start. After having it towed home I was startled to find a nest in the airbox and the air filter appeared to be clogged. This seemed like the obvious problem but after cleaning it out and replacing the filter the car started but died immediately. Since then I haven't been able to keep it running. My tech came to my house and hooked up his scanner. Code 45 stored rich exhaust. All parameters for the various sensors MAT, TPS, Crank position, coolant temp, no MAF on this car, all within proper spec. The fuel pressure is good for start up, spark is good although we don't know what fuel pressure is like after the car is running because it doesn't run. Cranks good battery good. Does the car still think it is getting no air? We are stumped. Pulled a plug, black and smelled of raw fuel. Installed new plugs, no change. What do you think
have the same problem?
