Yes, check the distributor cap for cracks. If a cap has cracks the spark will arc and you won't get full spark at higher RPMs. Also check the rotor and make sure it is in good shape, no cracks, the conductor is good, and that it is clean and dry. Also, pull out your no. 1 spark plug out and see if it looks like your getting too much gas. It should be dry with a dark brown color and not dark black and sooty.
