similar issues
I had Bill redo my ficm.The truck runs fine on interstate or 60+mph but I have cold start issues especially with the weather cooling down. I also have the heavy loping on start up and long warm up times. I have noticed a skip at lower speeds (40-50) in traffic especially up hills. I don't have an extra ficm to swap in and didn't have problems before the reprogram.I took my tuner off and the issues are still there. Any suggestions?
