I have a 93 GMC 2500 4x4 w/160,000. Sometimes it runs great and sometimes it won't hardly pull itself up a hill and sometimes it will just idle down and die.It will also sometimes on cold starts run real rough for about 5 minutes.I recently gave up replacing parts and took it to a very well equipped shop and left it for two weeks and told them to drive it home,parts runs whatever.They called me 2 weeks later and said they put over 200 miles under all conditions and it never stalled and had plenty of power. On my way home it died twice.Conditions,weather etc,dont seem to affect it.It is just a random thing. I have read several post and there seems to be some real experienced people in here so maybe yall can fix this problem I have had for about 6 months. Thanks P.S. It has been tuned up,fuel pressure is good,replaced temp sensor,knock sensor and the computer shows no faults.
