If i pump the gas, it starts faster. The car will always start it's just laggy. Next, my car shakes when i'm going up hill at a constant speed (not accelerating), my car shakes and stutters. After driving a while, when idling at a stoplight, the car will shake until i give it a little gas.. Also, my cruise control will not work. Does anyone have any suggestions??   Jeffrey Pinson (Jeffro0502) Member Username: Jeffro0502 Post Number: 41 Registered: 02-2003 Posted on Monday, May 12, 2003 - 08:54 pm:    Check vacum line from intake plenum to the fuel pressure regulator, very similar problem to what I had.   Damien Vrontisis (Dvrontisis) Member Username: Dvrontisis Post Number: 93 Registered: 04-2003 Posted on Monday, May 12, 2003 - 09:18 pm:    can you take a picture and draw an arrow to this particular line? i'm new to cars.   Paul T.

On the driver's side of the truck, above the valve cover, there is a round disc with a vacuum line going to it. On the in-board side, there is an arm that attaches to the throttle linkage. Follow the vacuum line back to the wing, there will be a tee with a line going to the bulkhead and the other heading for the front of the truck. They very commonnly break at the tee. I usually replace them all the way from the vacuum pump to the pedal. I believe the diameter is 3/32", but don't hold me to it. Buy a manual!!! The factory manuals are great, but the Haynes manuals will at least get you started.
