top end lagging?
it seems like once i get to 70-80 and i stomp it down it surges or lags, kinda feels like it does better if i lift the throttle a little... already did typical tune up stuff. any ideas?

Re: top end lagging?
Have you checked spark plugs? Does it feel like its kinda misfiring? I had a bad spark plug that was misfiring and it smelled like gas every time I floored it. Changed plugs, runs like new.

I was going to say a plugged cat until you said its better when you lift a little. It could be many things, TPS, MAF, coils, ICM, plugs, wires, etc...
Define typical tune up stuff.
Any codes?

Re: top end lagging?
tune up.... spark plugs (factory gm ones), wires, air filter... just the basics. I do have a code now its for the egr, ....could that cause a surge?
