Ok, My cotour has only 17,000 as of today. It is a 96 yes a 96. The other day the car started to 'stuter' and the check engine light came on. A friend of mine has a diagnostics machine and we hooked it up and it told us that there was a miss fire on cylinder 4. We cleared out the code and reset the check light.The next day I changed the wires and plugs thinking this might take care of the problem. (its the z tek by the way) It didnt, and the light is back on. We thought that since the mileage was so low that perhaps some carbon build up had broke loose and got stuck in one of the injectors so I've been running injector cleaner in it. It seems to have helped a little but its still acting up. Mostly when I try to accelerate quickly as to get into traffic from a stop. And of course the check engine light is still on. I have noticed that if I accelerate slowly, sometimes it goes beautifully and some times at higher speeds (45-50), it will stuter when I acceerate. Any ideas before I go pay Ford to much money to tell me that it has a mis fire in #4???????

My Car is doing the same exact thing, and I have no idea what could it be. I also posted a message but I dont think anybody else had that problem. If you do find out what it is please let me know, I have wasted too much money already. and the check engine light is drving me nuts. Good Luck.

Thank You, I will get the scanner. Thanks for the prompt response
