car keeps doing this. idk y. only when i hit it real hard it sputters.
What could it be. i have a d16y8.
only does it in high rpm. does it from mayb between 5k and 6k rpm
its a short sputter. does not do it constanly
i checked spark plugs and they are still good. i put new ones 2 thousand miles ago
NEW SYMPTOMS:
1. rpm needle bounces up and down between 2500 and 3000 RPM
2. when first turned on, car keeps cutting off, but once on for 10 minutes it stays on
* changed sparkplug wires for other used ones(does the same thing)
