Help! My LQ4 in my 1980 Camaro stumbles under constant throttle I have been chasing down issues with this car for months and I thought I had them sorted out but I cannot get this stumble/surge to go away (car was first started a couple months back and has not run right yet). It is present when I give it throttle as can be seen/heard in attached video. Does anyone have ideas?
