fuel injector change for chevy cavalier
hi i am the same guy who had an idle problem with my chevy cavalier 1994. after i fixed the idle problem, another one was realized. my obd is showing a sign of misfire on my third cylinder, and the first cylinder is running a little rich. the symptoms are hesitation on first gear initial acceleration after stoping. this occurs after the engine is warmed up. it even died on me on first gear. decreased horse power. this occured after i change the fuel injectors on my 1,2 and 4th cylinder. i left the third cylinder's injector old because it didn't have any leak or whatsoever. and now, the one cylinder that has the only old injector in is the one showing misfire. does that mean the the old fuel injector is the culprit of the problem. my may be sticking but. it didn't do that before i changed my 3 old injectors.
1. what are the other means to eliminate the other possible problem (just to make sure that i got the right target for budget purpse)
