HELLPPP!!!!!! F150 5.4L Cyclinder 4 Misfire
I truly need some quick help from some of you. I recently posted a thread and did not receive any responses. Here is the thread that I posted.
I recently had a Cylinder 4 misfire code on my 2000 F150 5.4 V8. I pulled the COP and found that there was water in the plug. The day before I had driven through a rather large spot of water in the road and it splashed up all over my truck. I contributed the water in the plug to that so I dried off the COP and blew out the plug.
Today, a similiar thing happened and within a couple of miles the misfire came back. The service engine light has come on but I would bet it is a Cylinder 4 misfire.
How could water be getting inside the plug. Could it be a damaged or defective COP or is something more sever?
Please give me some help.
