my idle is kinda weird
 

when i fiist got my swap my car was coo. a couple of days later my idle was kinda funny if would shake quite a bit, i went back and they changed my computer. it was better but it still kinda shakes like if it was an older engine getting warmed up. what can that be? can a be a ****ed up comp?

it might be some vaccum issues, or uneven compression in the cilynders

There are quite a few things that could be wrong with your idle. If youve already replaced your cpu, i doubt its that... it could also be your distributor timing, or your cam(s) timing... make sure the engine mounts are holding strong... hmm also might wanna make sure there isnt a lack of fuel going to the engine while idling... this could cause sputter, a condition similar to what you are describing... hmm thats all I can come up with now...
