Thanks for the reply Tim.

If it does turn out to be the ECU the good news is I have two spares (different) laying around somewhere. Hopefully one belongs to an 86.

I drove it a little and from my shop to my house 5 miles and it was good. I guess Im just going to have to wait until it acts up again. Hopefully it doesn't tomorrow because I have a wedding to do and planned on taking both of my vans down to do the job.
