Yeah, give that adjustment a whack without removing the cable. Your idle will be high on restart until the ecu remembers everything. Give it a minute for warm up then the idle should spin down.
I have never disconnected the TV cable. Just depress the "d" tab and pull cable to firewall. Get in car and stab the throttle until it clicks and clicks no more. Disconnect ECM power supply, reconnect.
I'm getting ready to install a full set on a clients car this weekend. It may be difficult to do because mike keeps sending me pictures of himself lounging in Maui.
I saw your car at Putnam!! Couldn't find you. I'd like to get a show together at our dealership in Mystic. Spoolfool said he's interested in contributing.
