HOW DO I CHANGE THE INTAKE MANIFOLD GASKET UPPER AND LOWER

From the codes im getting and the info I have, all the roads have lead back to intake gaskets being bad

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.

Disconnect Batt, splash cove over accel. Cables, remove cables from throttle body and air cleaner snorkle. Disconnect all vacuum hoses from intake ie. IAC, TPS, EVR, VIS and PCV. Disconnect Intake Manifold Tuning Valve(IMTV)remove brake booster hose. Remove 8 Upper intake bolts(see diagram). Disconnect left side Vapor Manegement Valve VMV(see diagram) clean surfaces install gasket torque to 62ft. Lbs.
