engine rebuild

[oldman_tau]

so i did my engine rebuilt top and bottom. Im curious, everytime when engine is cold, idle kept going up and down until it warms up returns to normal idle.

anything i have to check? thanks in advance

Boost leak is the first issue to address. Check the biss for leakage too. Once you have it all sealed up with no leaks, set the ISC properly and you should be good to go with no more idle surge.
