please help.
I've just turboed my mx5 and all was well (bar some tic and a minor oil drip(solved)) until I started it up earlier today and it spluttered/misfired and died. I can start it with a bit of throttle and have it "idle" if I keep my foot down a bit. It's fine under load I.e accelerating and over run. When I'm cruising it's misfiring. Also, it if burning a lot of oil.

ANY IDEAS??

 

i would not have been happy.
This is not the case here however as I didn't drill the sump. I've got a G19 return kit to the dipstick.

 

Well I can tell you why it's burning a lot of oil.

Regarding misfire: What engine management are you running? What spark plug gap? What wide band O2 sensor?
