If your idle is jumping up and down 9 times out of 10 its a vacuum leak or a dirty iacv, clean that, check for leaks and you will probably find your problem.

if you know anyone that has a smoke machine, try plugging it up, it will show you exasctly where your vaccum leak is, if indeed you have one. otherwise check your iacv.

Re: LS/VTEC problems HELP (B Series JuNky)
Have you tried any of the suggestions?
Idle screw? Brake cleaner to clean out IACV? Feel for leaks/fog machine for leaks on vacuum hoses? Reset ECU? Timing?
More time under the hood > more time on the internet
