'93 350 w/TBI surging below 2000 RPM
I have a '93 Suburban w/350. It has throttle body injection and is totally stock. I just replaced the throttle position sensor. The vehicle is "surging" at RPM's below 2000. Below 1500 RPM you can actually see the surging on the tach. When I come to a complete stop the idle drops way down. Any ideas?
