Another high idle .........

It's well known the older Rockets had inferior TPS's. Don't know how many miles on yours, nor your $$$ situation - But if your going to go to all that trouble, I'd spend the $130 & replace it. The replacement part is supposed to be improved over the ones made in 04 (I think I read that somewhere)

Thanks EasTex I have no problem fettling with the Rocket and trying to improve the way she rides ,just hate throwing money at a problem if not 99% sure its going to cure it! If the TPS is at fault why does it not throw a code on Tune ECU ?

"Another simple test from TuneECU is to just look at what TPS value (look at the Voltage value) when the idle rpm is high - what does it read?"

From memory when running some tests on Tune ecu read zero at idle and climbs to about 4V when revved a little, does sound correct?

IF the tps is suppose to read .072 volts at idle and it is reading 1.86 (stuck) the the ecu reads 1.86 and just thinks u have the throttle open a little and there is not a problem so no code.
in theory decosse is right however in practice sometimes weird things happen.
over the years mine has done the high idle and the running like $hit at idle it has never done it at a convenient time to check it every time i cleared it up by working the throttle also spraying the linkages.
