^ Yeah I remember you posting about your TB and I found the thread on the other forum about rebuilding them. I'm in the process of tearing down a spare USDM S5 turbo TB. I was actually going to work on it, but then found I was out of gas for my disposable torch.

So the fast idle is for when the engine is still warming up? Adjusting my fast idle does nothing. The sleaved idle is what I should be (and have been using to set idle).

ISC? Not familiar with that abreviation. I went through my grounds, or all of them I could think of and find. I did the grounding mod at the ECU. I cleaned up all the grounds down to clean metal. I've got the engine grounded on top of the keg to the firewall. I checked the engine harness ground that is on top of the engine keg. I have common grounds for gauges and headunit at the shifter bracket. I have another common ground at the driver kick panel. I went through my grounds for my stereo's amps. IIRC I got the one at the driver shock tower. I even got the one under the trailing coil. Right now my fan and alarm siren are grounded directly to the battery. Then I have an additional battery neg terminal to body chassis ground.
