Okay today I replaced my TPS as I thought this was the cause of my idle problem. I also search and found that I had two vacuum leaks where silicon hosing had become disconnected. So with everything back in order I am still getting the same problem.

My car will not idle below 1500 rpm, disconnecting and reconnecting the BAC shows no changes in idle either. It funny because a while ago I couldn't get my car to idle above 600 rpm then it just switched to a high idle, it seems like its always on cold start mode, and sometimes it idle higher as the car gets warmer, wierd. So any suggestions as to what is causing this would be much appreciated.

Also I want to see what codes the ECU might be spitting out, but I can't seem to find the connector that you are supposed to ground to get the codes to show up. There is a green connector on the driver's side but it has two plugs and not one as I have read about. So what's the deal, is this different on some cars or what? Can I use the two prong connector to see the codes too?

Thanks

 

Check to be certain the fast or high idle cam drops properly when warm. That might be causing your problem. When you check the BAC make certain the inner seal isn't leaking air. You'll need to remove and check, or disconnect the large air supply hose, then plug both the air hose opening, and the BAC tube and see if that makes any difference. I guess you can use tape to cover both.
