Vehicle starts and idles but stalls after warm and put in gear. Any ideas ?

[Tee Ell]

Another problem I had was adjustment - ultimately the curb idle was too low.

Ok thanks - It’s at about 840-890 rpm now

Hook up a vacuum gauge, then observe the symptom.

Have had the vacuum gauge on it been trying to find vacuum related issue so far no luck

A bad ECU can fail once the engine warms up.

Is the vacuum steady and how much?

If you still have the original distributor module with spark advance on the air cleaner I would replace it with a basic mopar ignition system. My 400 75 Cordoba had the same issue. Now it runs fine.

That tells me nothing. What is vacuum at start-up? What is vacuum at idle ? What is vacuum at part-throttle ? What is vacuum when throttle opened-up ? What is vacuum when put in gear ? What are the gauge readings and what is the needle doing at the moments I mentioned ??????

I’d recommend a carter carb tuning book and a tuning kit.. New fuel is terrible to run in our cars. Off idle can be tricky and may or may not be a lean condition..

Have you tried yelling and swearing at it?

16 lbs min on idle - steady

This year wouldn't have a lockup convertor. Unless of course someone's swapped them.
