the rpm shuffle?
88 5.0 and it does the oddest thing sometimes when in drive at idle with my foot on the brake the rpms will shoot up to 1200 or so then drop down to like 700 then back up and down etc etc. And when the rpms go up you can feel the car come under load then release when it drops......I was thinking tps but it only does it once Ina while. Any ideas?
