I have a 2002 crew cab 4x4 1500 with a 4.7 engine. I had a check engine light. the codes came back multi-misfires on 1-2-7-8. I change the plugs and 4 of the coils and get the same codes and misfires. Help please. Travis

 

Did the codes clear or are they still just stuck in the computer?

 

had the same problem before. changed the plugs and everything was alright

 

I'm assuming that you have a coil on each cylinder. I have the 2003 Ram with the 4.7. Check that nut/bolt/stud that holds the coil on. That acts as the ground and if there's a lot or corrosion, it could cause a misfire. What's the exact code that you are getting?

 

if its multiple misfiring it should beP0300 idf i remember correctly
