Default Re: running rough

misfire on #2 CYLINDER, no spark = bad coil. replaced with motorcraft coil problem solved. I am still going to clean the iac and other sensors while i am at this and probably do a seafoam for hits and giggles.

talked to a mechanic friend of mine about why it was not throwing misfire codes, response was; ford obd takes a bit of driving time before recording any types of codes. ?? fortunately I parked it and drove the e350 super duty until i had time to deal with it. my guess would be that pushing that much raw fuel through the cat would most likely foul it. Wonder what unburnt seafoam would do?

Thank you for the replies and help. I will update any performance increases with seafoam and iac cleaning.
