1987 Oldsmobile Firenza 4 cyl Front Wheel Drive Automatic
1987 Oldsmobile Firenza, 4-cylinder
Problem developed suddenlyandhas been intermittant.
Revs ok in neutral.
Otherwise, when pushing on the gas, develops loud irregular banging soundlike some kind of preignition or detonation, and power drops right off. Sometimes, one can regain some power by flooring it, other times this doesn't work.
Replacing spark plugs didn't help.
What could be wrong?
This is not a cherished classic car, it is an old beater that we are trying hard to keep running until we can buy something better. We live way up in the bush - not near any repair shop - so having any kind of sophisticated scan is not an option.
have the same problem?
