Re: CEL misfire #1 rough idle
This fits the profile of the classic EGR port clogging problem. The gases from teh EGR form deposits in the lower intake manifold and cause complications after a while.
To remedy this problem, you will need to pull the upper intake manifold and clean and scrape up as much of the deposits you can from the EGR nozzles.
Do a search in this forum for EGR and misfire for more details.
