I have a 1999 chevy cavalier that died & will only start if u push the gas to the floor & crank it over but it idles extremely roughly engine shakes & will not idle smoothly & will not rev up above 1500 rpm and is blowing alot of unburned gas out the tailpipe there are no codes being stored, I have checked the map sensor, fuel pressure, its getting spark to all four cyls. But spark is a yellow - orange color not blue. Compression was checked & all four were between 162 - 180 psi. Fuel filter, spark plugs, plug wires, air filter have been changed wuz wondering if its weak spark or if timing jumped or something else.
have the same problem?
