Puzzled...Advice Anyone?

Im rather confused, i gave my engine a spruse up and made it all nice and clean, and then after that it started running lumpy, did not get water on the main elecs before we say that lol, so i have changed so far:

Sparks
HT Leads
Rotor And Dizzy Cap

And its still the same, i did notice tho that the vac level on the boost gauge has gone down by 10? normal idle for the in vac was around 20, now its at 10 (if this helps)

I have checked for vacuum leaks and cant see much wrong, anyone else had this problem?

Thanks

See if there's any water retained in the TPS connector. It's upside down and might catch some fluids there.
