Default Idle running to low that it continuously stalls out

I have a 1992 D21 automatic that I just recently had a Nissan shop swap the intake over to a 240 intake. While they were finishing it up they fried my ecu. I ordered a new one. I installed it. Didnít know that a manual ecu would not allow the gears to shift when driving. So I ordered another one this time one for a automatic. Now the truck idles so low that itís stalls when giving gas. I tried clearing codes the other night but itís not throwing codes unless Iím not doing it right (I am new to this) Is there anything I can try do do. The truck is a complete show truck so the dash is not factory at all. only the motor is factory left on the truck. I am afraid to take it to another shop around my area. HELP!

You need to adjust the iacv. It's on the back of the manifold on the passenger side. Turn the screw in or out to adjust, should be set to 800 rpm.

Uhhhh -the shop is responsible for fixing your truck, it was their mistake, they're assumed by law to have expertise; if they fried the ECU, then they need to replace it/repair your truck at no additional cost !!!
