I seriously doubt its the opti spark. If it was i dont think the SES light wouldve come on, unless the car stopped. Id take a gamble on EGR or a fuel delivery issue at this stage.
The ALDL connector is under the dash just to the right hand side of the steering wheel. Join pins A and B together and then turn on the key. Dont start it, just turn it to on. Codes should then be displayed on the dash where the speedometer would normally be. Let us know what the codes are and we can move forward from there |
