i just got a 1989 supra turbo and its not running on all cylnders i dont think, i was told that the cas sensor was posibly bad?? anyone know a way to check them? im also going to check the obvious things today such as the plugs, wires, injectors and what not. if any one knows some of the comon problems with these cars and sensors i would appreciate any feedback, i dont know much about them yet, trying to lean somthing.

with the car running remove the plug wires one at a time. if your car idle becomes rough its fine. in your case if no change occurs.. lol

bummer. how did your plug / spark inspection go? wires in decent shape? spark plugs gaped correctly with no visual burning marks ?
