Cruiser54, is there a troubleshooting guide for the post-Renix HOs? I was following the Renix guides trying to T/S my son's 91 Comanche, but some of the steps are different enough that I did not want to assume the modifications. For example, I pulled the connector for the TBS, and I could not see any markings. If the pins are A - B - C, then my grounds are on A, not B. Was less than one ohm, so I did not split the wiring loom to re-do the ground connections. I did replace the CPS, even though I wasn't getting any CEL other than 12 & 55. One of the bolts holding the CPS was loose, and the sheath had contact something that melted the sheath, and one of the wires. Even after replacing the CPS, we are still having the miss issue. I watched the engine miss at 2500-3000 rpm range when I had the fuel pressure gauge installed, and the fuel pressure never dropped below 25 psi.

Could the partially grounded CPS (due to the melted wire) have cause an issue with the ECM? I have another ECM coming (that is the right number 56027532 provided by Hornbrod) so I'll get that swapped this weekend. 

Any other ideas?
