My friend gave me his 93 spirit which is in good shape for having 131K on it. I immediatly changed the timing belt after having suffered from other cars with bad belts and blown heads before, in which this car has had a head replacement already due to a belt breaking, and it ran great and still runs great after about 500 Miles on the belt. It has gotten much colder up on the NE and now It has a knock on accelleration which is didn't have before. I just did a full on tune-up and all is good. Car has power, and runs clean. It seemed to start after I changed my oil and added 10W30. Oil was dirty, and new oil seems dirty already. I added some Rislone with no help. Oil pressure seems strong and don't think its an issue.. I adjusted the timing, does it in any setting. I know these dodge motors have that slight knock to them, but is there any fixes besides a crank bearing job to alleaviate this? I added some higher octane fuel, seems to help but its still there.. Also My reverse light don't work.. They worked once in a while when he had it, now they just don't work at all. I know it has a reverse light switch on the trans. Is that most likely the issue? Any help is great! thanks!!
