I have changed everything on this car, plugs wires, distributor cap. and it still is showing a miss fire. does any body know why I want to change the injector but is that the right place to start.

 

I take it this is a 2.5?

 

did you do the park plugs to....?? Also did you put the plug wires back were there suppose to go as well..???

worst case this could be that one of your valves is bad and you will need some head work done to it.

After working on cars for a long time all motors are basically the same concept. My buddy had this same problem on his Celica and its was come to be that one of his valves was not working correctly therefore casueing the miss fire..
