Hey, sorry to hijack this post, but I adjusted my TPS not too long ago as well. Was set at base of .8 volts and I set it to .96 volts.
I couldn't get the WOT voltage set right though. The Highest I can get it to read is 4.0 volts as opposed to the recommended 4.9 volts. Could my TPS be bad? The throttle plate does open all the way.
Any Ideas on this related problem.
BTW, when I set the base voltage, It corrected my erratic idle problem.
