My vacuum drops from 15 to 12 on a vacuum gauage tester after 1 minute exactly from starting it. It runs like its missing and i don't know what is wrong wit it, it hasn't changed performance or anything just idle. I have an E303 cam and many bolt on mods. It started idling like this right after i changed the spark plugs and wires and added an adjustable fuel regulator and had it smogged. Anyone know of the cause or has had this happen before? I've replaced almost every smog part since it started and it has had no effect.
thanks,

I would double check and make sure that the ignition wires are goining where they should be. If this is messed up it can cause a rough idle and backfiring.
