i have had the same problem once and it was due either the wires or spak plug fouling i changed both and solved the problem
TCC Solenoid.
Common problem with this engine is the ignition coils.
you may need a new carborator
I would suspect it is not timed correctly.
Either the timing is excessively retarded or you have a worn camshaft or related problem.
IF... the crank sensor was the problem then it might. However, it is unlikely. I agree, although they are known to crack, It usually results in a no start condition from what I have seen.
Try changing the fuel filter.
Incorrect installation of the chain. It is backfiring because the timing is off. Remove the chain and do it again correctly.
Bad head gasket and/or cracked head.
I have a problem. I just bought a used 1995 Kawasaki 220 Bayou. The engine started running a little rough at first. Kept getting worse and then started backfiring through the exhaust. I had the carbeurator rebuilt but still runs rough and backfires. Cranks good and idles good. What could be my problem? Thanks
go to autozone or other auto supply store and ask for a "flasher" for your year make and model. i just hate this problem on my 94 corsica.
Hmm, I had a similar problem with my Ranger. It had an untraceable electrical problem, and we sold it for scrap. Symptoms include backfiring, severe loss of RPM before backfiring, dying unexpectedly, just about everything it shouldn't do. How bad is the sputter? Does it sputter, or does it sound like a large dying animal?
