a couple weeks ago i drove to town (2 miles) and my stratus died as i entered my driveway and would not start. it would turn over but not fire. did fuel system check and all was good there. check engine light was on, so i had 2 friends with different scan tools come over to check it out and neither tool would read the code. at that point (out of curriosity) i tried to start it and it fired up and ran great, after about 20 min. it started misfiring, wouldn't gain rpm but would idle, then just die and not start untill it had cooled off. i replaced the plugs, wires, and the ignition coil pack today. it fired right up, ran great (again for only about 20 min.) started thinking that it might be plugged up cat. converter so i went to pull it in my shop to pull the exhaust off, it started right up but now it only has spark on cylinders, 1 & 4. barely ran long enough to get it inside. checked spark at the coil and have good bright arc on 1&4 and nothing on 2&3. i have checked compression (good all the way around) i took the new coil off and put the original back on with no change. checked engine ground straps, (good), i have checked wiring connectors (look good), moved wires around while engine is running (no change) any help would be greatly appreciated :)

    the new coil you put on might be defective or you might have an ecm problem

    after alot of questions and diagnosing it did come down to the e.c.m. found one at a wrecking yard for $50 !! :) whole lot cheaper than $290 new. if anyone has the same problem make sure you get the same emissions (california or federal) that way you dont have to worry about any reprograming issues. so far car is running great. thanks for the input guys, much appreciated !! :O)
