C4 Engine Stalling
I have a 1994 C4 with the LT1 engine.
What will cause the engine to stall out either at a stop sign or when turning into a driveway. It only will occasional do this and it starts right back up. No trouble codes are being set. I am currently in Wisconsin working and my wife is driving the car in Charleston SC.

IAC would be my first guess. I'd definitely clean it up by removing it, take off the top, IAC, IAC housing and clean everything thoroughly . After that, check fuel pressure and spark quality

The best way (by far) to approach your issues is to scan it and check for codes. Without scanning first, there are a number of things that can manifest themselves in the symptoms you're describing. Scan first, replace as needed, save $$$ and headaches!

Often, it is hard to get people to buy a scanner.

The car was taken to a local Charleston SC Corvette (They only work on Corvettes) specialist and scanned. No trouble codes and they had no issues when test driving. This has only happened twice in the past month with my wife driving the car. I am currently working a contract job in Oshkosh WI.
I will ask my wife to have the shop check the IAC before she picks it up.
