Does anyone know how to adjust the idle on a 97 Supra. My idle has always been to low on my car even before the single. I don't believe there is anything wrong with the car, it idled fine with the 95 ECU. The 97 ECU just idles about 150 rpm's too low.

Thanks, Steve

thats the throttle cable your pointing to. if anyone knows where to idle i need to know also. i heard that the bigger the turbo the more the idle should go up to circulate the oil to the turbo or turbos during idle. about 1000 rpm sounds nice.

I don't believe the throttle cable is the correct way to adjust idle. The cam the throttle cable mounts on should be at a specific location in reference to the throttle position sensor. Typically there is a screw that lets a cetain amount of air bypass the trottle plate, but I don't see one on the Supra. I also see no mention of an adjustment in the manual.

I tried upping my idle as well. The ECU lowered it again, and throttle response suffered. I guess you'd have to ajust the TPS...

What Larry from SP recommended was to T the two power steering vac lines together, that will raise it.

I thought about adjusting the throttle position sensor. I guess I can give it a try. I may just call Larry and see what he thinks.

I used the the throttle cable as well and just reduced my accelerator play to a minimum, which I like now.

There is small nut that screws into the throttle position where the car is reved. I am sorry I cannot describe any better than this .. but if you look in that area you will see it. I just unscrewed it and increased the length of the screw that when the cables is lose it doesn't go down as much.

Well I can't really say if it really help my idle but it doesn't flutter that much when it is cold. Again I would like answers.
Thanks

Hey Steve if we could get together soon I think I can help. I put the HKS ETCS-less kit on and my car was idling too high. I found a way to lower it but it's too complicated to explain. It should also apply to raising yours.
