When I start my pilot in the morning, the idle is rough and could stall until it warms up
rough idle when cold on 2004 Honda Pilot
I would have your valves checked. I had the same thing happen with my Prelude. Cold start it ran like crap for 1 minute and then smooth as silk. I had 1 tight valve.
What can cause my 1994 Buick Century to run rough when cold. It runs fine after it warms up
This engine has an idle air control motor that could be functioning incorrectly. I see tight valves affecting idle and emissions as well.
