Hello everyone. This is my first attempt ot use one of these forums so be gentle with me. I have a '89 F Superduty that sometimes smokes and stinks and other times runs clean. The local Ford dealer suggested using Summit brand fuel system cleaner and that worked for the first tank of fuel the it was back to the same problems. Any help would be appreciated. Thanks
