Hey Everyone, In November I got a GM factory rebuilt 350 put in my 1988 K5. The place that did it is called NECO's. Since the new engine has been installed my oil pressure is constantly at 60 and the check engine lights goes on and off frequently. Also the K5 has shut off on me at least 10 times. I took the K5 back to NECO's and they said the coumputer has no codes in it, and they don't deal with computers. What can I do about this problem? Is there more than just replacing the computer I have to worry about? Thanks for all your help, Tommy Insomnia is your friend!
