Did not suffer this malady before the great clean out . Now the 2.5 ATX seems to have the throttle hang issue or more appropriately throttle rise . All is normal - cold idle returns to 700-750 rpms , no hunting for rpm at start up etc .
When crusing (all speeds) and I let off the pedal the rpms either hold or rise 1000 rpm ?
Do I just do the TH fix and move on ? - or IAC ? both ?
Did search ! but no real solutions for "throttle rise"
Advice appreciated .
