I've always started with coil packs and plugs on these . Scan it and see if it's got random cylinder misfire or a particular cylinder in the stored codes.

If you pull any of the plugs out and there's oil there you'll need to do lower intake manifold gasket and a full valve cover gasket set with plug tube seals.

Might be worth cleaning the injectors also while you're there and a fuel filter if the external easy type.

As Harrop.Senator said I would get it scanned for error codes first. Although I am far from an expert misfiring while accelerating would make me suspect coils first of all.

I also suspect coil pack as I can go out and it goes fine for a while then just starts from no where

Thank you for the info

if your going to change coil packs, change plugs as well
