intermittent rough idle?
 

Doesnt matter cold or hot, sometimes sitting idleing and sometimes when i pull up to a stop sign it will drop to 500rpms and get real rough, i can give tap the accelerator and it usually clears up.. noticed the fuel pump is very slightly leaking from the weep hole could this be introducing air into the fuel system? anybody else have this issue? seems to run fine all maintenace is recent and runs fine off idle.
