Re: 89 tbi idle issues
I think I have the Blazer running better. When I sprayed Carb cleaner around the shaft that goes through the TB with the butterfly valves on it and it started running better. Yesterday I pulled the TB off and took it all apart, then put o rings on the shaft. It seems to be running way better already. It seems I had a vacuum leak around that shaft causing terrible idle issues.....
We will see how it goes. |
