My check engine light went on I went to AutoZone had them tested it came back misfire on plug 3. I changed the plug still doing the same thing. You can smell gas in the car while you're going sometimes and it goes real slow. It shakes when you're idling. Change the control module, same thing. Change the tubes and the springs they connect to the spark plugs still having the same problem. Can you tell me how I can fix it?

Hello,

This could be a problem with your vehicle's Electronic Ignition [EI] Module. In the diagrams down below I have included a description of operation of your vehicle's EI Module, Connector view with callout, and the factory step by step instructions for the removal and installation of the EI Module. I also included the OEM part number for the EI Module for you as well. Please go through these guides and get back to us with what you are able to find out.

Thanks,
Alex
