Gilly, Thanks for the info. Could you possibly tell me where the throttle motor is located on the E-420 and also the location if I need it the fuel relay, is this the same relay as the fuel pump relay, if it is I do not think it would be this relay because I can keep the automobile running by keeping the gas pedal down for a higher RPM other than idle speed. I do beleive that you may be right. Just do not know where the throttle motor is located. Thanks, Ben
