Hi rrembert,

Blue smokes indicates oil is being burnt in the cylinders or are leaking into exhaust via the valve seals, replacemtn of the valve seals would help.

Surging is mostly caused by a fault with the idling system :
1. Lack of coolant in system or clogged IAC coolant hoses.
2. Faulty IAC.
3. Idling speed too high. Adjustment might resolve it.
4. Leaking vacumn lines.
