94 Vitara surging? timing?

[Deadduck]

compression is good 170 cylinders leak down test 1-5% all ok only has a slight miss at idle or when i get water over dizzy cap or ignition parts CEL is off comes on key on engine off so fine no cat been gone for a while now never had this problem till now code is 24. I will check fuel have not done that yet but its only in certin RPM ranges and it is constant everytime it does it. as i got reading down WOT is the problem that is where it does it. When I put my foot down it is bogging until I hit 2500-3000RPM not set time but more like a set rpm. notiiclble most on hill I wanted to pass/ speed up so change from 4th to 3rd and WOT bogs till i hit 2500-3000RPM every gear.

I Will do some more tests
thanks
