I have read many posts on this code on TW and do understand the multiple misfire code.
My 2001 2.7 (140,000 miles) started misfiring a few months ago but only until the engine warms up to operating temp. Once warmed up the misfire stops and everything is fine. The misfire is quite apparent when shifting gears. This winter has been really cold and after 10 minutes of driving the problem goes away....the CEL just came on last week.
I am guessing it is not plugs or coil pacs but maybe the MAF ?......I do have the deck plate mod done 2 years ago with no issues.
Any ideas are very welcome regarding my misfire only when engine is cold?
