Engine running rough under load
I've got a 99 Camaro SS that is basically stock. Lately, the engine is running really rough when I try to accelerate hard. It runs smooth at idle and is also smooth if I ease the throttle on. If I try to accelerate much at all in 6th gear it starts jumping. Even in the lower gears, when I open the throttle up a little too hard I can feel the engine missing bad. Any ideas? I'm going after the other 4 plugs Saturday (see my other post), but it seems too harsh to just be plugs and wires.
