Car idle poorly on cold start. Shakes badly when cold.
What is your question?
Problem only occur when cold. Took idle speed control out and cleaned. Took ECU fuse out and disconnect battery cable also to reset ECU without any result. Once car is driven for awhile rough idle goes away. Once operating temperature is reached it still takes awhile for idle to Smooth out. What could be problem? It's evident that something isn't getting the right information to kick in and work on cold engine, to smooth it out. The power is there, does not stable, and runs well. Just idle like shot when cold. Has 234.000miles.
