trying to help a friend with his 04 Sebring convertible 2.7. He has had it many places and replaced loads of parts. 1st it blew the #4 plug. Hole was tapped new plugs, #4 coil and injector replaced. New valve cover and intake gaskets. After that car died randomly throwing cam and Crank sensor codes so both were replaced. Then when the car was warm turned on defrost to have the car would die. The car would also die when coming to a stop. No fault codes. Battery and alternator were replaced. Car now does not die but when stopping, holding windo switches to long, or heavy load the engine bogs down.
