running on 3 cylinders?

[1badass97]

well i changed the spark plugs in my car. it was running fine for about 15 minutes then started acting like it was running on 3 cylinders. ive had people tell me its a bent valve? im thinking maybe an injector has gone out. or could it be in the coil pack? i also pulled each of the plug wires off while the car was running and it didnt change the sound at all. any suggestions on what it could be?!

try to isolate which cylinder that isn't running. i had a problem with this when i first got my talon... make sure your injectors are tight, your spark plug wires are tight and pushed all the way in on the head and on the coil pack. also check to see if youve fouled out any of your spark plugs. hope this somewhat helps..
