I just purchased a 1997 Ford Escort Wagon with a 4cylinder 2.0 litre engine in it and I can't get this thing to stay at an idle. There was a problem that I found out after I purchased it, and that being the car sat for 2 yrs, because the people I bought it from said the motor was locked up,which I couldn't get it to turn with a socket on the crankshaft and they thought that the timing belt was broke. I repaired the ground wire that was corroded, took the timing cover off, found that the timing belt was in good shape, but loose, got the engine to free up reset the timing and tightened the belt. I replaced the spark pugs, checked the resistance on the wires, and checked for a broken or bad vacuum line. Any help would be appreciated.
I have a 1990 Oldsmobile Cutlass Ciera with a 3.3L V-6 engine in it , that backfires through the throttle body while trying to start, if you crank it over and hold the accelerator pedal to the floor it'll eventually start, it'll idle rough but if you speed the engine up it'll smooth out. Also if you put it in drive, hold the brake and press the accelerator down it'll go " pop pop pop " The car has 218,000 miles on it and it has a clack clack clack noise coming from the passenger side of the engine. Could it possibly be the timing chain bad or has the timing jumped?
