Just try to keep the gas and drive for at leat 15 min HWY if possible. Yes, it will turn off if you let go the gas, but it will restart and stay on as long as you press on gas. Just keep on driving and the computer will readjust the emission inputs and will get back to normal.

Most likely cause is a leak in the valve cover gasket. Under pressue, a good sized leak will spurt and burn off on the manifuld, causing the smell of burning oil you're getting. This also would cause the presence of oil throughout the engine compartment. Best of luck on your problem.

Check the hoses - especially all the little 10mm hoses that connect vacuum pipes, etc.
There is a device in the throttle body called an Idle Stabilisation Valve - they get gummed up, especially on such an old car, and with NZ's low-petroleum fuel - lots of additives in NZ gas.
They are easy enough to clean - look for a lead plugged into the throttle body near the butterfly - you can unclip it and pull it out complete - they are usually about 15cm long, by about 4cm wide.
Spray it liberally with carb cleaner and make sure it can move freely. If not, a wrecker is the best bet - they are pricey new.

Testimonial: "Hey Zoot, thanks for that, its great advice but I have one problem.. no idea what an Idle Stab. Valve looks like. see my comment on orig ques. "
Don't have a good answer to your problem but the items I'd change would be the coolant temp sensor and the manifold air temp sensor if yours has one. Both will influence the condition you have posted. Also, the rpm's you noted are on the high side of safe on normal cold starts but because in extreme cold the engine oil takes a while to get where it needs to be, I'd consider using a good synthetic. It flows easier and stays on parts without draining off, giving a bit more protection.
