Question about Cars & Trucks
I would be suspecting a faulty condenser and coil as when they reach operating temperature they start to break down electrically.. Check that the auto choke is coming off and not tending to over fuel the engine

Testimonial: "This particular cutlass has HEI. No condenser or points. Is the ignition module the part that replaced these parts and is there a way to test? Auto choke does come off. There is no smoke out exhaust."

SOURCE: ROugh idle
there are 2 things that usually cause this, one is a dirty intake idle control valve and the other is hard engine mounts, I would say that both most likely apply to your car. try cleaning the intake with the following procedure from Ford.
Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

i melted my module off of mine 89 gta once on my disturbertor and also had the plugs that snaps onto the coil pack cause a lot of problemns because it wasn't snapped all the way don on the coil pack not the plug wires but the wiring harness plugs and it gave mne a lot of problems.may want to check yourself took it to a dealer ship 4 weeks in a row and every time they said it was fixed i drove it for a couple hours and it would quit and not start and that was all it was but it started with a tune up wires, cap ,rotor button.

Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps
