Service engine light and gas light came on. Code read at autozone indicated po135- oxygen sensor. Two days later, both check engine lights came on, security, battery and gas lights. Even revved up and had other issues with fuel economy and compressor kicking on and failing to start. Other issues, popping noise when turning steering wheel.
Every Buick owner, I have talked to at about 80,000 to 100,000 miles has to replace intake manifold and bolts. This is about a $1200. 00 job, gaskets and bolts should last a lot longer.
