Just goes to show you, don't by cheap parts. Still runs a little rough but just won an auction for a snap-on 2500 scanner so will finally be able to do some test as per saig in the

Update, after overhauling the heads, adjustable fuel pressure regulator and new MSD opti-spark it turn out to be the computer. I sent it to 4 places and finally the last said it was fried. Well after finding out it was impossible to find one I asked the last place what to do and they gave me the number to a place had not only one but two ECM's, it was $650 but my corvette is finally on the rode running great. Thanks all for you help
