I Have An 89 Prelude Si. Sometimes It Happenens, Sometimes Not. After Warm Up, It Starts With A Misfire/chug. You Can Hear It At Idle, But Notice It Under Power. The Car Will Jerk And Make A Popping Sound. I Know Its Cutting Out. When I Push In The Clutch And Rev It Up....everything Is Great. Engage It In Gear Again,...misfire. It Does This Until A Check Engine Light Comes On.then It Runs Smooth Again,a Noticeable Power Loss...but Atleast It Runs Smooth Across The Board.almost Like The Engine Switches Channels Or Something.
I Have Done Tune-up,ect...

I Haven't Changed Any Sensors.map,o2,ect...

Any Ideas?
