5.0 Ho Swapped Comet Lean Backfire Issue

There were a few times right after getting the car that I could not get the Innova tool to get the computer into diagnostic mode. My buddy's Snap On diagnostic tool also could not get the car into a KOER test.

That was intermittent though. It has successfully run KOEO, KOER, and cylinder balance tests with the current computer. I haven't had that issue in the past week or so.

I suppose if it is an intermittent issue, it isn't likely an O2 harness/computer mismatch issue.
