i got a 95 240 with the stock ka24de. car starts up fine but idles rough as hell. i replaced the plugs and wires but nothing changed. i unplugged the #4 cylinder spark plug wire from the spark plug itself and the idle didnt change. i put it back then i unplugged the injector on the #4 cylinder but nothing happened. is this an injector problem or do i need a new distributor?

this would cause the injector to stop working completely?

is your injector clicking when plugged in?

to listen for the click use the screw driver techniqe
take a long flathead put the tip on the injector and your ear at the top of the body and listen for the clicks.

compare it with the other injectors.

If you dont hear the click replace injector

if it runs like shit, it most likely is not the 1 cylinder, i agree, break out the timing light.
