Question about 1991 Ford Aerostar Extended
I recently changed the spark plugs because the van was missing. I didn't notice any improvement. It runs really rough when it's cold but gets better as the motor warms up. I just filled the gas tank so I don't think it is a fuel problem. How can I check the coil pack? and/or what else should I look for.
Did u also change the plug wires? and you could also change the fuel filter, air filter, and the oil and filter. and if you have the know how you can take off and clean the throttle body
