My 1993 olds cutlass supreme idles fine until you step on the gas or when your going down the road at higher speeds than idle it has a hesitation what's the problem?

A flat spot on acceleration could be low fuel pressure or a faulty throttle position sensor. Could also be a vac leak such as a faulty EGR valve.
Is the check engine light on ?

How do I replace the EGR valve in my 1999 Ford E350 van?

Your vehicle has an EGR valve attached to the intake manifold. About how to replace an EGR Valve, check this procedure...
1. EGR Valve

1. Scan Tool
2. 3/8 in. Drive Ratchet
3. Wrench
4. Socket Set

Step 1 Locate the OBD-I or OBD-II data link connector (DLC). Refer to your vehicle owner’s manual for the specific location.
o Tip: The OBD-I data link connector is usually located in the engine compartment near the battery or the fuse box. The OBD-II connector (post 1995 cars) is usually located beneath the instument panel next to the steering column.

Step 2 Turn your key to the“ON” position. Do not start the engine.

Step 3 Plug your scan tool into the DLC and follow the manufacturer's steps to read the diagnostic trouble code. Codes between P0400-P0408 are generic trouble codes for the EGR system.
o Tip: The OBD-II diagnostic trouble code (DTC) is a 5 character alphanumeric code. The first digit is a letter that indicates the component group, the second digit is OBD mandated or manufacturer specfic, the third digit is a subgroup, and the fourth and fifth digits define the component and basic problem.

Step 4 To test the EGR valve: Remove the vacuum line to the valve and install a manual vacuum pump. Start the engine and apply vacuum to the valve. If the engine idle speed drops, the EGR valve is working. If the engine idle speed does not change, the EGR system is not working. Most engines will stall if you fully open the EGR valve while idling.
o Tip: Some vehicles are equipped with electronically controlled EGR valves. Use a scan tool to test these valves.

Step 5 Remove the vacuum line or electrical connector from the EGR valve.

Step 6 Remove the EGR mounting bolts. Remove the EGR valve.

Step 7 Using a new gasket, attach the new EGR valve with the original mounting bolts. Torque the bolts to the manufacturer's specifications.

Step 8 Reconnect the vacuum line or electrical connector.

Step 9 Erase any codes on the scan tool through the“delete” or“erase” command. Remove the scan tool.

Step 10 Road test your vehicle to verify the repair.
o Tip: If the check engine light returns, repeat the diagnostic process for additional DTCs or take your vehicle to a certified repair shop.

Check the RIGHT PART before to take off the parts. Its possible that you can find few TSB in your library or dealer about this LINK.

Hope helps.

Old ford fiesta stalls when i come to a junction engine revs die if i rev up

Hello, yes the problem could me related to a vacuum leak around the intake manifold or carburetor area. What technicians often do is listen for vacuum leaks or spray some carburetor cleaner spray (can) that you can get at an auto parts store around the rubber vacuum hoses to locate the leak. If the engine speeds up when your are spraying, you have located the leak.
The other problem that likely comes up is the EGR valve opening up too soon or when the engine revs and this causes the engine to cut out. You can block off the EGR valve to trouble shoot the problem. If blocking off the EGR valve solves your problem, then you know where the problem is.
