As of late, my 88 XJ has had some low idle issues. When its fully warmed up, idling in drive at a light, the rpms will sometimes drop down to between the first and second mark, the idle will be a little rough too, but it will sometimes catch itself, idle around 800, and then back down again. I seafoamed, didnt help and no smoke, TB and IAC were cleaned last fall, dont see how they can be THAT gummed up already, and if it comes down to it, ill check them again.
When I searched, all I came up with is High idle symptoms, and no help with low idle.
Any ideas?
