LONG post> Machine has seen mud. Checked T-bap, found bare wire's fixedpull's code 41, have fixed, we think, main thing is all wiring has been checked and fixed bare wire's in loom from mud rubbing and breaking insulation down. He has completley gone thru evry wire and still breaks down. Has pulled a code 45 once andpulled 46 for t-bap. Clear's code's run at idle no code's.Take's out and run's WOT and still has intermitent miss at high rpm's, gets t-bap code. Take my t-bap off mine, which is fine, still has same problem.We have service manual and cannot figure out. I know this is a reach, I may have to have him give complete info to you guy's. All I know is if we cannot troubleshoot this, we WILL HAVE NO TROUBLE SHOOTING THIS THING WITH MY WEATHERBY MAG>
