Pro Flo 4 Timing

the tps needs to be 0 or 1. That’s where toy have to start.

I understand, the ECU sets TPS Zero at key on, but it'll refuse to return to zero while driving. I've checked for binding or restrictions in the cable and linkage, but haven't found any.

So it will idle properly for a while, then it will float high enough (2%) to disable idle speed control after driving for a bit.

After synching the distributor at 12, I rotated the crank slightly to 30. You’ll notice the rotor as way far from the terminal on the number one on the cap. Essentially, I moved the rotor closer to the terminal on the cap. It’s off to begin with and when the timing advances it’s firing the next cylinder.

Good info, once i try a new TPS Ill take a look and see if what you found on yours is also on mine. It's either a design issue or a QC issue.
