I have a misfire that is driving me UP THE WALL. When I first start the car, it misses on one cylinder. After it warms up, it fires on that cylinder, but only until I give it a little gas. It then misses until i let it idle again. Under heavy accelleration it doesn't miss.

I have replaced the plugs, all the top end gaskets(minus head) the wires look good and almost new and the motor doesn't make any noise.

I cannot tell which cylinder it is because when i try to diagnose it, it starts running correctly.


I am thinking bad injector, anybody else?

 

That'd be my guess. When it does that again, shut it down and start pulling plugs and see if one is gas soaked.

 

YOu can also pull injector wires to help diagnose
