Question about 1991 Oldsmobile Custom Cruiser
Vehicle- 1991 oldsmobile custom cruiser
remanufactured engine installed 6 yrs ago, 30k miles on the "new engine".
The tranny was rebuilt 3 times, last time was 13 months ago. cv joint replaced and rear end replaced 2 yrs ago.
passed Ga state emissions right before problem began, only had to get a new gas cap. I had the oil changed at goodyear, 75 miles before problem started.
steps to solve problem I have taken-
new exhaust system, catalytic converter fine.
new fuel filter.
new spark plugs.
higher fuel octane.
Been looked at by 2 garages, problem not found.
This problem has been occurring for 4 months now, only been driven 400 miles in that time.
coolant level was low once, but the car is not overheating.
Upon starting the engine- at times, it will lope and surge unevenly, slight vibration. Sometimes flooring the gas while in park will solve the problem.
Other times, problem will get worse- until the vehicle begans to lose power/slow down w/ gas pedal depressed- if the gas pedal is pressed down harder, the vehicle will shudder violently for 45 seconds to a minute- but it will "push thru" and eventually pick up speed. The shudder is getting much more violent as time goes on.
I would appreciate exact possible problems to have checked, most mechanics don't know my car and are at a loss- I have twice been asked to buy a new car bc they can't fix this one.
I can't afford a new car right now- if anyone knows of a mechanic in the Atlanta metro area who knows old cars- I would appreciate the contact number/email.
