Dont if id trust that method u used SM6989. I say this because i unpluged my TPS during my Idle surging hunt and it idled perfect with it disconnected and that wasnt even a part of the problem. I would vouch for vacuum leak somewhere. If anything though just go pocket a map sensor from the junkyard just in case lol

 

yeah it wasnt a map sensor..still the same.

 

I unpluged the TPS but it still idles high, Could that still be it? so I know if I should get one.

 

Could always test it. Hook a voltimeter to it. One end on ground and the other on middle wire. It should be .5V closed. But it sounds more like a vacuum leak then anything.

question does it only do it when warm or on cold idle also?

 

It does it all the time..I cant find where there would be a leak though.. Anyone here care to help me out and take a look? lol I'd offer some cash. I'll try that with the sensor and such then post back.

 

did you check your iacv? take it off clean it then put it back on should be fine thats what happened to my hatch g/l

 

Yea id do a cleaning on IACV and maybe take a look at the FITV while your under there. Both take same amount of time to check.

 

DId both...same thing..Although it idles at like 2k now instead of 3k. Tried lowering it but no luck.

 

it idles at 2k with no more surging? or is it still surging?

Have you checked to see if maybe your throttle body was too tight or perhaps something is keeping it stuck open? When i first got my rex my a6 would hold a 2k idle and it ended up being breathing tube from valve cover to intake that somehow got sandwiched between the throttle valve.

you tried lowering it via idle screw on TB?

LMK,

Thanks

 

Now its back at 3k..it dont idle surge when I take the TPS off. Tried the screw. no luck.. I just dont know lol..and its getting annoying cause the car has tons of other problems with it.
