The other day I was driving to work and noticed a stumble or hesitation at 1900rpm under low load (1/2 throttle tip in). It hasn't done this before.
At first I was blamed the fuel I put in. When running regular, it pings under WOT. With premium, this goes away. But even with premium, it still stumbles.

I changed the plugs and wires this summer, so that can't be it.

I don't have a timing adjuster....maybe I should get one????
Can it be my fuel filter, TPS or throttlebody????

Any suggestion would be apprecaited.

Thannk,
Steve
