I'm driving a 1988 GM injector sedan. My MPG ratio had suddenly
dropped after it was taken out of storage, having stayed in an outdoor
garage for 2 years (California). MPG dropped close to 15%, which
After I took it out, I only flushed oil, and burnt several tanks of
gas. Air filter was changed before the storage, spark plugs/wires - 6K
I have no computer codes.
Would appreciate ideas.
