Car does fine except a occasional low speed miss but high speed 50 plus missing bad. Ude fuel cleaner frequently but all gas is 10 % ethenol. Plugs and wires changed 40000 miles ago.

Scan for codes and check fuel pressure with a gauge auto parts rent it . also check for a vacuum leak like broken line etc.
