whats up fellas i got my turbo gsr tuned and have been driving it for awhile and its been fine but its devloped a high idle...in the morning when i start my car it idles at 3k which i know it supposed to idle high when its cold but not that high once it warms up it comes down to 1500 but my wideband says its like 15.0 16.0 which is pushin lean now this is at idle...when driving the car it runs fine and dosent run lean...ive checked everything i cant find a leak anywhere...i figured you guys may know something i dont...thanks in advance

 

Prob got an idle valve sticking. Clean it out and see what happens.

 

ok so it wasent the idle control vavle..ive checked every sensor and every vacum nipple..the intake manifoldit tight.. i took the charge pipe off and put my hand over the tb and the motor shut right off...im stumped...can it be in the tune anyways..my tuner says its a small vaccum leak but i unhooked the blowoff vacumm line and left it open and it picked up 500 rpm..so it has to be something else to make it idle so high...any ideas guys

 

It's strange how it's come from nowhere. A map shouldn't just change.

I'm not sure what age your engine is so not sure if it has the FITV (Fast idle thermo valve), but if it has, take that to pieces and clear it out.

It does sound like the symptoms of a vacuum leak... does it hunt at all or are the revs just steady all the time? Could a pipe of split anywhere around the inlet mani?

 

im having the same issue. almost positive its a vac leak even though im having trouble finding it.

do you have a boost/vac gauge? ive noticed that im only getting 20" at warm idle when i normally get 22", further indicating a leak

 

turned out to be the plastic had came unscrewed in the fast idle vavle cause air to leak nuy all the time..i cleaned it all up and tightend back down and it works fine

 

that will do it..too bad i have no fitv. o well back to hunting for my leak
