Hey everyone. My boss has a 94 Ram 1500 360. It hasn't been above 0 degrees here the last week. Sunday, the truck had a hard time starting in the morning. Sunday night, it didn't start. We had our Towing buddies bring it in the shop where it's always about 55 degrees. It's been in the shop for a few days now. We changed plugs, wires, cap and rotor and it still didn't start, we held the gas pedal to the floor and got it running. Now it runs bad. It will start, and idle ok for a while, then it kind of surges. When you rev it up you can feel it missing. When you hold the gas around 1250-1500 it backfires and pops and misses. Our snap on scan tool didn't pullany codes except for 37. We changed the MAP sensor, the coil, the CAT, put a new battery in it, Changed the Crank position sensor, still got the same problem. We check the fuel pressure, it's fine. We are getting clueless. We dont know what to do. Anyone had this happen to them before or know what could be wrong? Please help us. By the way, we're a diesel shop so we're notused to working on cars, that's why I'm asking you guys. Thanks for any help in advance.
