Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** vehicle act like it has a rpm limiter such as not wanting to go over 3000 rpm? Thanks.
This is a common problem caused by a clogged catalytic converter. Completely remove front oxygen sensor from exhaust, if that allows it to run better the converter is clogged and needs to be replaced. This would be around a $300 job at a exhaust shop. Let me know how it goes or if you have more questions. Thanks.
