1990 corvette random stalling issue
My 1990 Vette runs perfectly 99% of the time but then will randomly stall or you hear it start to die and then the computer manages to recover the idle. The computer is running a moates emulator and is re-programmed for a Vortech supercharger install. Are there any other sensors that could be faulty and cause the idle to drop off suddenly. Ive recently fitted a new o2 sensor and new distributor.
Any help appreciated. I have a Tech 1 but not trouble codes at all. As I live in New Zealand nobody knows these cars so I wont be able to get local help.

I did have major noise issues when I first put the emulator on and programmed it via a USB cable with the car running. Im told USB cables are very prone to noise and when I programmed the emulator with the car off it sorted the problem. MSD ignition wouldnt help for noise but no live tuning for me.

Hi Jim
I found a post as per your comments "fix to Moates Ostrich issues on '90 and newer"
Very similar to my problem and Ive just shortened up my ostrich ribbon cable which was quite long.
Ran the car for 10 minutes or so with no issues. Ill give it some time and report back. Now to post my next thread which is quite different if any of you can help!
