Back from hunting and working on the Rover again (did not take Rover).
Correct on the running and poor performance. Tuning could certainly be off as I was unable to get a good tune based on the timing light / TDC and my tachometer doesn't work, so I tuned it based on sound and idle position that it didn't stall out on but still allowed it to fire back up again. The idle sounded higher than it should be. The tach wire is connected to the alternator but doesn't seem to work and I'm not sure why or what exactly else I should look for.
The Y-Pipe has O2 Sensors with wires but I can't seem to find anywhere for them to plug into? If I recall correctly, before I brought my truck into the shop for this project I don't believe the 1988 with the 13CU had O2 sensors. The guy shuffled a lot of parts around while he had his shop and I believe he mentioned swapping the Y-Pipe out for some reason, which could explain why I can't find anywhere for them to plug into.
If I could get the tach working I might be able to better tune it. If in fact this thing is supposed to have 02 sensors maybe there is a way I can hook them up.
Yes, the crankshaft, connecting rods, and pistons were swapped to 4.6 as well.
I'm pulling the injectors out today to see what they're like.
Any other thoughts?
Thanks again!
