My 87 shelby z kept idiling about 1500 rpm after coming to a complete stop,it gave code 15 so i replaced the speed sensor,still did it ,so I pulled the ais off a wrecked 88 automatic daytona es car,and the problem was fixed.It started doing it again a few weeks later,so I pulled the brake booster hose off to reset the ais,but the ais motor wouldn't pull the idle down like it should.My question is,can the ais go bad and not show any fault codes? I only have the 55 code....thanks.........I pulled the ais off and have a friend turn the switch on and it felt like it was vibrating but the pintle didnt move,and you can't move it with pliers...the other one that was on the car first,you can push the pintle in and out with no resistance......what is supposed to happen when you turn the switch on with the ais off the car?
