What does your PowerLogger show in the 'Prog Idle' box? It's the one under the IAC Counts box. - I'll double check but I think it was somewhere around 900
As far as a vacuum leak,I replaced my 23yr old hoses after finding some that were attached,but were more partially stuck on,than properly attached. Many looked good on the outside,but were hard and crumbly. - I have been replacing the vacuum hoses with the same hose but haven't finished.
Got new ones from nos4gn.com. Under $4 for 72 inches of each size. Shipping was faster than a speeding bullet.
Have you done the carb cleaner spray test for vac leaks? - I haven't tried this yet. How do you do this?
Do you hear a hissing sound at idle?- I can't hear a hissing sound but the engine is loud and it is hard to pick up a hissing sound.
The 1,600rpm idle is indicated on the PL and not by the inaccurate factory tach. ?- It shows on both the Powerlogger and the Scanmaster.
I put another chip in that I had in before the TT chip and the idle went down to 1300 RPMs. I don't know if that is low enough for the emissions test though.
