4.0L sohc.
PO171, PO174, PO301-PO306, PO430, PO001

I have replaced the spark plugs and wires. I just purchased the tps today and so far that is it. I had a diagnosic test done about a week ago and the garage said I needed to replace the intake gaskets. I have also cleaned the MAF and replaced the fuel filter. It seems to consume alot more gas then it suppose to and until it warms up it will idle rough and stall out unless I hold the gas and it will stall out while Im driving sometimes. I also hear a whistling sound while the truck is idle position

Check that air cleaner box is secured tightly and snorkle is clamped tight. Then at idle lightly spray carb cleaner around throttle body and upper intake gasket. If a leak engine will idle smooth when spray is on leak.

You want work from the center outwards. That's usually how the ones that require sequence are, but here is more on it:

Upper Intake Manifold Nut 20-25 Nm (15-18 ft. Lbs.)
Throttle Body Bolts 8.5-12 Nm (6.2-8.8 ft. Lbs.)

Here are diagrams that have more information below

Check out the diagrams (Below)

Please let us know if you need anything else to get the problem fixed.

Cheers
