1991 Chevy Caprice V8 Two Wheel Drive Automatic
hello , i have 1991 chevy caprice classic with roughly 150k on it.
one day i was coming from work , driving in highway doing 65 then after i took the exit stopped for traffic light , my car started shaking with rough engine idling & loud exahust sound.
I took it to a local mechanic who told me to change spark plugs , ignition wires , fuel filter and even TBI unit , i did all of that.
The problem still there with poor fuel economy + engine seems less powerfull than before+ difficulty starring the car.
can you help me , is it oxygen sensor , bad catalytic converter or PCV valve.
P.S : the emechanic did not have code scanner.
