I have a 89 GT then all the sudden started to cut out or sputter at any RPM range stock 5.0 new plugs cap rotor wires new fuel pump new O2 sensors . I've checked for vacuum leaks with smoke machine nothing leaking how to replace the TPS idle air control valve coil and I'm getting gettin stumped and I do have a video of the car what it's doing but can't load it up here files too big so if anybody wants me to send it to them to see what it's doing I will do that thanks for anybody's time and help I appreciate it

Does it just shut off. If it does , and you dont mind throwing parts at it get a ignition module. It goes on the distributor. Check your grounds ,look them up. While irs stumbling move the wires around like the salt and pepper shakers. Somebody else will have some ideas, those are mine.

You can go through this checklist step by step

Help me create the "Surging Idle Checklist"

Updated 26-Oct-2019 to clarify creeping idle RPM increase as the car is being driven. Many of you are familiar with the "Cranks OK, but No Start Checklist for Fuel Injected Mustangs" checklist and the No Crank Checklist. They are very effective in finding and eliminating the problems by use of...

Or you can waste time and money changing parts.

I hope I never have to do the checklist again. Tough, but fair.

I found the problem it was the ignition module on the distributor it was an aftermarket Excel and IT literally broke apart inside put the stock one back on it and it runs great

You mean Accel which is now owned by Holley. Excel is a spreadsheet program owned by Microsoft.
