RPM Oscillation on Idle

[dreaming-of-driving]

Hey guys. I left my car standing 3 months, charged the battery up and tried to start it. But on cold idle it bounces between 800 and 1000 rpm.

I expected the problem to clear after it warmed up, but after the engine is warmer the problem is worse and the engine cuts out completely.

It really doesn't seem to be the MAS since I cleaned that thoroughly 6 months ago.

When the accelerator is held down it will stick to a selected RPM normally, but the engine blows a lot of smoke. Any ideas? Thanks

It must have been gummed up. But that happened faster than expected..

I added fuel injector cleaner (red type '5 star') and 100mL eucalyptus oil, revved it awhile and now it runs smoothly.

That's a relief, I've got mine locked up until the spring. I think I'll be adding a redex or similar just to aid the old fuel through the system.
