injector questions

[smithm5]

so my car has about 105k miles, epl chip, piggies, and exhaust.

recently i had 1 injector fail on me. first thought it was plugs and changed (they were shot anyway) and didnt solve the issue. still misfired on 6, when idling, driving, load, anything. you couldnt "make" it happen. we replace the injector with a stock "updated" one and great! a week and no issues.

now it seems the car idles considerably rougher than before, and doesnt appear to pull as smooth. is it possible that it could be due to a nice new clean updated injector when all the others are old?

Not really. If anything it should run SLIGHTLY better than before (unless some other injectors are failing now too).
