when i accelerate i dont have a problem at all my runs great just constant power, however when im cruising at any speed my car sorta jerks backwards and forwards almost like it feels like it cant get fuel to the engine!!

and half the time it idles ok and the other half the revs go up and down and it sounds like it is going to stall... what sort of things should i be checking for here???

check the idle control thingy too, mine was all gunked up and was causing all sorts of whacky problems at idle (hurrah for the stalling automatic :P)
dont know about the cruising though

so i figured it only does this for the first 5 mins or so of driving so it might be an idle issue.. over fueling perhaps?? im getting it tuned this week anyway so im hoping the problem goes away.

I would be checking that IAC valve if I were you, my guess is it will be gunked up.
