So...I am finally getting down to checking all m vac. line, TPS, IAC,..to solve my rough idle issue. Well first all the vac lines are good..second on to the TPS. So I notice right away that there is copper wire showing were it enters the connector. The sheathing has slide down maybe a half inch away from the connector. I'm guessing this means There is most likely a problem there. My question is how do I disconnect the connector from the sensor? I am afraid I'm going to break it...and we can't have that, at all costs.
