I'm pretty convinced it's a electrical issue rather than a mechanical one? When u first start the rig it idles like normal say 700rpm.. When it reaches operating temps/gets a bit warmer.. Revs can go anywhere frm where it sits right up to arnd 1500rpm... If you turn on the aircon the revs will drop then after a while it will idle up again all by itself? Cars starting ok.. If it don't start first pop I just flick the key on and off a couple times and it will fire right up.. Gots me stumpd on what it could be... Disconnected crank angle sensor no different. Temp sender and also boost sensor... Sand papered and cleaned up the earth connections going to the intake manifold.. Changed the blue relays arnd still no diffrence...
Might need to buy an ECU-TALK $250 or go to Super Cheap and see what error codes come up.
BTW idle is 750RPM,
04 ST 3lt auto, not enough Mods to keep me happy, but getting there
its not throwing any codes... last code was apparently injector pump.. i think it might have a lose wire/conection going into the ecu... wheres the ecu in these bad boys?
According to the manual under the lower instrument panel RHS.Originally Posted by mullet_hunter
I suggested the high idle switch before but reading the symptoms you describe its revving too high to be that. Have you checked the Throttle Position Sensor and wiring? Maybe its not sure where its at so its trying to find a reference point for the throttle.

I havnt checkd tps.. but i read somewhere that someone had similar symptoms and it was a lose wire going into the back of ecu...my blue leds just turned up today so i gota throw them in behind the instrument cluster so will have a look for any lose/dodgey wires when i do that.. also managed to crack my radiator shroud.. not impressed.. lol.. so brittle.. anyways blak n gold saved the dayy until i decide or get arnd to replacing it with anew one...
LOL I prefer Cadburys but its all a matter of taste I guess. Good luck with it mate.
