My engine runs fine when it has had 5 - 10 minutes to warm up, but sometimes, not always, has rough idling and misfiring when the engine is started in the morning. I replaced the fuel filter because I did not see where it had been replace before and it was a cheap thing to try. I have tried to use iso-HEET and SeaFoam to help the problem, but nothing has proven to work. I would get codes, but the check engine light isn't blinking when I would be able to get to the store to check it. What are your thoughts? What's my next move?
I guess I really want to know if this is something I should just drop off to a shop or can I diagnose and fix on my own?
