04 Mustang GT surging on hard acceleration

Cheers all. I own a 2004 mustang GT manual. I've been chasing a very annoying problem recently. When I'm accelerating at full throttle my car surges and bucks. I've replaced all 8 sparkplugs and the fuel filter with no luck. After looking thru the menu on the dash the car is throwing a D262 and an oil pressure switch code. I don't see how these would affect the car in this way. I would deeply appreciate any help that could be offered!

I am chasing the same issue. I am curious to what suggestions come of this. (Mine has no codes)

@jcarroll2180 - If yours is doing the same as mine, you can accelerate normally and the engine is smooth but as soon as you get on it, that is when it is beginning to buck correct?
 
Then we are having the same issue.

I have new plugs and wires, new fuel pump, new fuel filter. I am also idling at 2g which I do not like. Saturday I will back the idle screw all the way out and see what happens. I do not expect to fix it this way though. Something we have in common is causing this issue.
