Extremely poor acceleration and 5.4 MPH
Dear Sirs, I inherited a 1993 Chevy Lumina Euro with a FI 3.1 V6 eng and auto trans. 102,000 Miles. It had not been driven for 16 years and stored in a garage. It had problems from sitting,,, the usual, brakes tires battery. No mouse damage! The car looks Great, almost NEW! I replaced the Spark plugs and spark wires, got a mechanic
to check ignition coils and for computer codes, there are none. Yet I have a VERY strong smell of unburned fuel from exhaust. EXTREMELY poor acceleration, and getting only 5.4 miles per gallon. Checked eng. compression it's fine. No eng knocks or noises. I have never seen anything remotely similar! I am loosing it over this problem! Will you help Please?
Thank you David Comstock Sr.
