Havn't been able to find an answer searching so i thought i'd just ask.

A little backround: redtop, jwt ecu, 550's, cobra maf, gt30r, stumbling idle, occasional misfire, hard cold start (but thats b/c of bad fpr).

My problem started when i measured the output voltage from tps->ecu it was .1ish closed and .6ish at WOT, and it wasn't getting much higher when i tried adjusting it. So i replaced the tps and of course the problem continued. The tps was only getting .6 volts from the ecu (power to tps). Checked resistance on hot and ground side of the sensor and everything checked out and tried another ecu and got the same readings. What should the ecu->tps voltage be and why would it be low like this? Seing as its late right now think simple, b/c i probably overlooked something stupid.
