Hi all,

My favorit has been off the road for about 18 months. On starting it up again it runs ok for few minutes then the idle speed Starts hunting

after a few more minutes hunting it settles but at the higher idle speed, and exhaust gets a bit more smokey

First thought was maybe coolant temperature sensor making it run rich but pretty sure that was one of the things I changed 3000 miles ago

any other suggestions?

cheers 

Check the spark plugs, the throttle, the Lambda sensor, change gas station for 1-2 times, change the engine oil-oil filter.

By the way charge your battery too and when everything is checked make a journey with high rpm.

I took the airbox off again and rechecked all the connections, charged the battery as previously it was off a jump start and now all is well!

It happened to me few years ago, the screws of the hose clamps were a little bit ''loose'' and more air was coming into the throttle.

It's not something easy to see, especially in Cold weather there is a tiny material delation.

Fully recharge the battery with a charger that can go low and slow as possible, 2 or 3 amp charging better than 4 or 6 amp but will take a lot longer.

 

The day after the full charging check the battery for (state of) charge and if possible state of health, a poor battery could hinder your recommissioning whereas a good battery in good state of charge and health will possibly speed up recommissioning and help with keeping the whole car going well.
