You have a flow restriction,the orifice tube,(inline filter) on the low side(suction)a/c hose.Check close by the dryer and lines for freezing over,if so evacuate,then flush a/c system,install new orifice tube and recharge with new oil and freon.

The orifice tube located between the front grill and the a/c condensor in the upper a/c line.You will need to pull the grill off to get to the orifice. ---------- Thanks.Helpmech.

It is located inside the condensor tube running to the evaporator.

Here are the removal/installation instructions as per alldata:

TOOLS REQUIRED

J 39400-A Halogen Leak Detector
J 26549-E Orifice Tube Remover

REMOVAL PROCEDURE
-Recover the refrigerant. Refer to Refrigerant Recovery and Recharging.
-Remove the air cleaner assembly.
-Remove the vacuum brake booster.
-Remove the condenser tube.
-Use J 26549-E in order to remove the expansion orifice tube. IMPORTANT: DO NOT use any solvents or chemicals to clean the porous plastic inlet filter of the expansion orifice tube.
-Inspect the expansion orifice tube for the following conditions and clean or replace with a new tube as indicated:
-Broken plastic frame (1); replace the tube.
Inlet filter (3) damaged or plugged with fine gritty material; replace the tube.
Inlet filter (3) coated with metal chips, flakes, or slivers; remove the coating with low pressure shop air ONLY and reuse if the filter is cleaned satisfactorily. Do NOT reuse the O-ring seals (2).

INSTALLATION PROCEDURE

IMPORTANT: Lubricate the new O-ring seals (2) with mineral base 525 viscosity refrigerant oil.
If you reuse the orifice tube, install new O-ring seals (2).
Carefully grasp the edge of the expansion orifice tube (1) without touching the inlet filter (3) and insert the expansion tube into the condenser tube until fully seated.
-Install the condenser tube.
-Install the vacuum brake booster.
-Install the air cleaner assembly.
-Evacuate and recharge the A/C system. Refer to Refrigerant Recovery and Recharging.
-Leak test the fittings of the component using J 39400-A.

you can use open end wrenches. just make sure the wrench fits well or you will round it off. i would use line wrenches if you have any. try not to tilt the filter when you get it off or it willl pour out.

You will cee a thin A?C tube running towards the evaporator core housing. The tube will look like it is connected to another tube. Ijnside there is the orifice tube

it is located in the high pressure line coming from the condenser. that is the smaller of the two lines and it is the lower one. its approximately 10 inches back. look for the indentations on the line near the fitting. they look almost like a crimp. they are there to stop the orifice tube.

a/c orifice tube is on discharge line before filter dryer side the line.

Check or replace the EGR

Check all vac hose for cracks first if never been changed and look at all the T connectors as well
Next would be check MAP sensor and all components associated with the EGR and Fuel
