Question about 2002 Buick Regal
2002 regal would slow down going up hills thought calatic converter then cruise would not work then then acdcelrates to 70 mph without using gas pedal then enging cuts in and out goes to 3000 rpms drops to 2000 rmps then back to 3000-now when yuou start it engine reves up without holding pedal down - on highway runs at 60 mph white engine cuts in and out without holding pedal down
The catalytic converter most likely is no the sorurce of the problem, older design bead type Cat converters used to plug, but it is very rare on the newer ceramic honeycomb cats, u need to have the electronic engine control tested, are u getting a check engije light? if not has the fuel filter been replaced every 30,000 miles? also a part called the Mass Airflow sensor can cause these symptoms as well as igntion system problems.
