Races to about 2800 rpm, then drops off quick to about 200rpm shoots to about 1300 rpm, then levels out to 800-900 rpm.But,this ussually occurs
after a re-start on a hot engine.
Mine also has the surging 900-1,200 RPMs...I think this is common
to alot of 86's..
...it also has that lumpy exhaust sound. Isnt that what a 5.0L with headers,dual exhaust supposed to sound like ???
