Re: 1990 Chevy 4x4 low speed miss

Thanks for all the help. I think we are closing in on the problem. Due to all the work on the 91 transmission today I was not able to do much with my truck. Wifes 91 always comes first. Happy wife, good life. So I disconnected the egr valve today and this eliminated a lot of the problem. Still a little rough but not as bad. I also noticed a hole in the y pipe today just close to the oxygen sensor. Wondering if that may have anything to do with it. Anyways I am going to the city tomorrow and will be back to the truck either Sunday or Monday. I will let you know how it is after I remove the EGR and clean the valve and port. Have a good weekend and enjoy your time with family. Thanks.
