So I’ve got a 1988 GMC Bluebird Short Bus. Runs well, no issues with it really, except it surges at idle, especially when you first start it up. Evens out a little bit if it’s been running a while. No issues at all while driving.
Maybe about 100-200 RPM, tops. Maybe not even that much. But it’s a little unnerving, enough to where people ask me about it when they’re in the bus.
So I’m wondering if anyone else has this issue, if it’s normal or not and how to troubleshoot and look for potential fixes.
Thanks to all who take the time.
Short video attached. Hopefully you can hear it. You can definitely feel it when you’re in the bus.
