hi guys and gals...

just bought my first RX-7 its in great condition, oil pressure is healthy, boost seems healthy, the only thing is that is running a bit lumpy between tick over and about 4500 rpm... anyone got any ideas.. could ir be running a bit too rich?

could it be the worng type of oil?... what do people here use... I am running 10W/40 mineral oil, dont know what the garage put in the car when they serviced it... I know it has the right plugs in so I am assuming they put in the right oil.... would it be worthwhile changing the oil... I am getting it serviced by a specialist in about two weeks

hope tog et an answer soon
