2004 Endeavor: Misfire Help
First time post on the forum. I am trying to help a coworker with her daughters car. 2004 Endeavor with 257k on the od. They are trying to keep it going, so I volunteered to see if I could help.
Problem #1 - CEL for a misfire/coil failure for cylinder #4.
Engine was obviously missing. Swapped coils. Problem followed the coil.
Replaced coil. Engine much smoother. CEL for now a simple misfire. Checked coil connector - cleaned it. Erase code and turned on the CEL withing a few minutes.
Will pull the plug and take a look. They have run many thousands of miles like this. So I am not sure if I have a plug/injector issue or perhaps a bad ground/wiring issue with this wire).
Any other thoughts?
Problem #2 - The water in HVAC / Blower Motor issue
Pulled the TSB-09-55-002 and read the posts here. Believe the blower is fried from the drain being blocked and plenty of wet carpet on the passenger side.
Should I evacuate the A/C system and pull the dash or does this TSB at least help the issue with periodic maintenance? Or, must this be done in conjunction with the Cabin Filter for a longtime fix?
Thank You.
