Hello. My truck is not takin the gas properly. U can press the gas but its still pickup real slow. Plus u can drive it for awhile an it will just cut off. Truck will start right back up but will not have much press. U might can go up to 20 mph or less. I had the truck service complete. I changed the gas filter. The filter was stopped up. Now the truck is still cuttin off. Could u plz tell me what that could b

Buy yourself a vacuum guage from the parts store and connect it to manifold vacuum and tell me what kind of reading you get (please give extensive detail on range of vacuum, the time of deviation, and if the needle vibrates).
