I replaced my spark plugs semi-recently and my rpms go up right with my pedal, but for some reason the power isn't transferred that quickly. I drained my tranny fluid, no metal shavings or anything. Anyone ever have this problem? Any ideas what it could be?

Im having a simmilar problem, did you find the problem? when i bought my 2002 4 door blazer someone had already changed the plugs and wires and maybe the cap and rotor, I managed to get a multiple random missfire out of it after stomping the gas. im guessing cap or maybe they used those cheap crappy wires and its got some bad wires already. any advice will be helpful. i also had a similar problem but with added back fireing and poping in the throttlebody, on my '92 astro vin: Z. turns out on it i had a combination of a lower throttle body gasket leak and a slowly failing ignition coil. maybe the case with the 2002 blazer.... if anyone has advice or a cure please let me know, thank you!
