TPS voltage readings
OK 1st a little back ground on the problem.
The car was flooded pretty bad and I got it started back-up let it warm to operating temps then took it for a spin, at WOT the car would back fire and buck violently at around 3500 rpm. When smooth on the accelerator the problem was not present.
I did hours of searching and found some pretty helpful threads, I figured it was a fouled plug so I changed the plugs and still have the same problem, I checked all the vacuum lines and ground connections everything seems to be ok , after some advice from a knowledgeable forum member I checked the TPS voltage.
my readings are as follows
0.56 - 4.55 on the 3F ECU wire
0.2 - 1.20 on the 3G ECU wire
Now I realize that's way off and not in the proper range. I tried to adjust it but could not get it any better. My question is could something else be causing this or is the TPS bad for sure.?
I don't want to start throwing a bunch of money changing parts and not solving the problem.
BTW the car was running fine just prior to being flooded.

wires go from the ecu right to the tps, so either the harness is bad, and or the tps
