do you have any way to datalog the ecu?
does it run this shape TPS on the TBI unit
there are 2 different versions of this tps one turns backwards compared to the other and can make the ecu go into clear flood mode when cranking

It looks close to the same but my book says it is non adjustable type. Could this be causing an issue because its gotta be moved slightly?
But yes it seems the ecm is going into clear flood mode when cranking.
Measure the voltage at TPS. It should be around 0.54 If it's way higherr like 4.5v then it is backwards.

Cool I will do that. I didn't know what the voltage was suppose to be so that is helpful. If it is somewhere like 1.5 would that mean it is off a bit or something? Just curious.
I Will post my results when I do it.
