Snizzlesticks

So after a few weeks of driving great my truck will randomly loose it's acceleration to varying degrees. Then randomly it'll run great again. I got a memory code of 32. No codes at all for the running test except for engine ID. The EGR valve looks to be newer and from advanced auto. Should I start instead with the egr solenoid? Or is there another way to test them before I go buying parts I can't return.

I forgot to add, if I really keep it full throttle for a while which I don't like doing, it does seem to temporarily improve somewhat. Not sure if that helps. Learning as I go. Gonna try cleaning it tomorrow.
