Thanks

Have you tried a cold engine leakdown test?

If the problem occurs only while the engine is cold, you may have a problem with the lifters not properly causing the valves to seal off. Once the engine warms up, and the metal inside expands, then the valves seal better and your idle returns to smooth.

It is a simple test and it can give you lots of info about your engine's condition.

Good luck and let us know how you eventually solve the problem.
