K6 600 to k7 750 motor swap issues...!

Nice - congrats.

Glad to hear your problem is resolved but... you did a voltge drop test on the TPS and the result was .3 parasitic resistance. Really? You've combined three incorrect terms in one sentence. The result of a voltage drop test is a V measurement. The term parasitic refers to a draw on a circuit and is measured in amp. Resistance is measured in ohms, and when you're talking TPS that varies with throttle position.
There is a lot of good help here but you need to provide accurate technical info and terms to get the most out if the GTAM brains.

I just summed it up. I did resistance, and voltage drop test but I didn't feel Like typing the specifics.
