Maybe you can start by telling us what you have done to the car.

By Cobra cam do you mean the E-cam? And what is your idle set to?

I had the same problem, the cam is what's causing the issue.
I recall we tried several things to get it to stop shutting off but I dont think that any one of them was the answer by itself.

My car in park idles at about 900-1000 (Keeping the idle high helped)

I also have a custom chip. (Also helped)

And I have a Pro-M Optimizer. (It connects to the MAF) When I got this and tuned the car with it all the shutting off issues ended. I dont know if it was a combination of all three things, but its very possible that the optimizer is what fixed the problem by itself.

1994 cobra cam E303.
Despite what you may have read or heard, the "Cobra" cam and the E303 are NOT one in the same.

If you search around youll see that this is a fairly common issue with the e-cam and automatics.

you only need to drill the hole if your out of idle screw....i think im at a 3/16 hole......if you have a cam in a auto you need a converter....did you try to clean the idle control motor??

We got mine to work prior to the higher stall converter on the Lentech. Again, in my case im pretty sure that what finally got it settle down was the Pro-M optimizer.
