ok two days ago my car started hesitating on the throttle...now its gotten to the point where it wont move also i started the car and tested each plug by pulling the wire from it, all except 4 change how the car idles....could i have a dead cylinder..

ive replaced:

spark plugs and wires

oh yea...car idles great

no cels from the ecu i can start the car and pull the plug wire off of cylinder 4 and the idle doesnt change but my spark plug is firing and so is the wire coming from the dizzy

Any other symptoms? Does it sound odd, different than it used to? When you say the plug is firing, how do you know? If you've had it out of the head so you can see the spark and the engine ran the same as when it was in the head, it sounds like you've got a bad valve. You might want to check compression on all four cylinders or pop the valve cover and turn the motor by hand so you can see if one of the valves is stuck or broken.

failling of the TPS sensor ??

speedometer stopped working, and it does sound diffrent like its missing and yea you can here the plug wire popping before it connects to the plug but that sounds like its true or could be the problem ima check the valves 2mar thanks man

when you pull the spark plug wire to see if there's any changes, if there any changes, then that cyl. is good. if there are no changes in idle, then that cyl. is dead or weak. didn't you say that you just had your t belt replaced? or was I thinking of someone else?

Okay you've got fire to the plug how do you know the plug itself is firing? Could be as simple as a bad plug.

it sounds to me like it's a fuel problem.

this is a different motor but yes timing belt is new and no i get no change in the idle when i pull the plug on cylinder 4 and i know the spark plug is firing because i tested it...and saw spark...i heard it could be a valve???

Well lets see get a compression tester on that cylinder. Make sure fuel is firing into the chamber.
