Hi,

We have a 2002 Dodge Ram Van 1500 with a transmission that died and was replaced. Before the engined died, we were getting O2 sensor error codes and the speedometer would jump all the way up and back at any time, while driving or standing at a red light. So the transmission was replaced and when we went to pick it up, the radiator was leaking. The radiator was replaced.

After a few days, we have new engine codes, P0031, P0037 and P1495. My wife says she has seen the speedometer jump as well.

Any ideas? Suggestions? No one seems to know what to do.

Thanks

Bob

No need to go to another site. All of the codes are in sticky threads up one level on the main page for this here forum.
