2003, 2.3 4cyl bad ignition coil, learning tool
I wanted to share this with others who may be learning too.. I had a off and on problem with acceleration, cutting back, hesitation etc.. idle was fine! never did this all the time just once in a while.. I figured it was fuel, vaccuum or ignition related... replaced some vaccuum hoses, fuel filter etc. changed plug wires and it got better... that should have been the red flag! finally this crack appeared on the ignition coil housing.. replaced it and runs perfectly! the obd tester never picked up the fact the coil was bad.. this one was a trial and error.. good learning lesson for me! hope it helps you too!
