Engine Performance problem
1990 Chevy Lumina 4 cyl Front Wheel Drive Automatic 104560 miles
I have a 1990 2 door Lumina Euro - Bought the car a couple months ago - ran sweet for the first month then the ECM died - we replaced it as well as a faulty crank shaft position sensor and a worn alternator belt - car starts now but its burning a very fuel rich mixture - to the tune of about 3 - 5 miles to the gallon! Hooked it up to a sensor and got the code for a faulty MAP sensor - went to the parts store picked one up and installed it, and the car won't turn over at all. Replaced the new MAP sensor with my original one and the car starts but with the fuel ratio issue and super rough idle - its also blowing a LOT of carbon out of the exhaust - took the MAP sensor back to the parts store and got a new one in case it was faulty but had the same issue - engine won't even turn over with the new MAP sensor in. Any ideas what to do next?
have the same problem?
