well my b18 has been running really rough....ever since i put the fuel press regulator on last week. i set the gauge and drove it...it was ok, but once in a while it studdered and was acting like it wasnt getting much gas...or had a lack of back pressure
i put the stock fuel press reg back on...same effects. all plug wires were firing fine. then this am i changed my plugs i pulled the plug wires out..and there was this sorta slugde on one (only a little)...and rust colored dust on another (on the plug wire base). then i pulled the plugs out...and it was wet...not oil...didnt smell like gas. but was wet. so i tried to dry out in the plug wire shafts and replaced the plugs. reset the ecu and it ran fine. no stutter or sputter. so i got in and drove it down the road. first gear fine, second gear...started doing it agin..third and so on.

so i left it...my pop told me to change the fuel filter and get some gasoline water treatment.... he says he thinks it sounds like a little water in the fuel....any ideas??!?!

please help....
