I have a 98 Stratus with about 150k miles on it. Never had any problems until a few weeks ago. I had a blowout on the bottom radiator hose. The engine overheated and stut down. I replace the hose and the engine ran fine for a week and then the check engine light came on. I ran it for a few more days and lossed power and then seen alot of smoke come from the exaust the engine shut down and would not start. After checking the engine I noticed the knock sensor was melted in half. I replaced sensor and the engine will not start I checked the spark plugs an they seem to get spark. The fuel pump is ok. Do I need to reset the computer or something? My brother thinks its the coil pack how do I test it? I'm also thinking about replacing the starter relay. Any thoughts?
Thanks!!
