1992 cadillac sedan deville, 156,000 miles auto transmission was doing 55mph and the car excellerated to 90mph on its on and got stuck. When I opened the hood the ISC motor was engaged all the way out holding the trottle open. The car stumbles on a full take of gas, on 11 gallon of gas, and on 5 gallons. These codes came up after the ISC motor got stuck E41 camshaft position circuit fault, E48 Exhaust Gas Recirculation system fault, and E98 Transaxle shift fault. Please help before this car kills us. Thank you

E41 will make the car not run, cam sensor in distributor

there is a test through the climate control for the ISC motor, first look down the throttle plates, is it carboned up bad? If it is the TPS could be sending the wront info to the computer causing the ISC motor to extend. Take to a cadillac dealer this is a timely process, carbon cleaning and idle and TPS set up and ISC check out
