    Im having a problem with rpms slightly dropping and then returning to normal, but it does this while I'm accelerating. It drops between 50 to 100 seems kinda sluggish. I put on a new fuel filter, air filter, ran injection cleaner, took off the tb and cleaned it completely. Someone said a vacuum leak. What do yall think?

    what iowa said. more info would help.


    I would go through and check all your rubber vac lines and elbows. over time the hoses and elbows get very brittle and start falling apart. I had to replace all of mine. any same size diameter heater hose will work IF that's the issue.

    is the fuel filter on the proper way?? meaning the arrow on the filter is pointing towards the front of the truck.
