Weird RPM Dip
Camaro Rookie

Hey guys...
Was driving home Friday and noticed my 'maro just wasn't running right. It's a '95 3.4L V-6, and at around 60-70 MPH say I was coasting down a hill with my foot off the gas.. when I get back on the gas pedal, the RPM's will rev up to 2500 then back off to 2000. Also, the car won't down shift right. Used to be when I floor it at 70 mph, the car would accelerate up to 85-90 with a quickness. Now, when I floor it, yeah the car does downshift, but it doesn't sound like the rpm's are as high as it used to be (don't know what it used to be 'cuz never had to pay attention to it.) And now it takes 10 seconds (eternity) for it to accelerate from 70 to just 80 mph.
What I've done:
Took out the coil packs and read 'em out with a multimeter, and the resistance on the primary and secondary's were on par with the specs. Cleaned 'em up and put 'em back in.
Anything else I should do? Any other info that'd be helpful in narrowing it down?
Any help is really appreciated.
Thanks guys in advance!

"the RPM's will rev up to 2500 then back off to 2000", any chance you could clarify that a bit? Are you saying that when you get back on the gas, it increases to 2500, and then upshifts and backs off to 2000?
