The adventures of BIG FLEXY continue. Last week she got a new wheel bearing and i guess she wanted some more drama. Yesterday i was at work and wife called me saying her 2009 Ford Flex was bucking like a bronco. I have replaced the same ignition coil twice on this car, both times using a cheap coil from amazon. She is 60 miles from home when she makes this call and I am still at work and cannot leave for hours. Told my wife who doesnt know much about cars to roll up her sleves because she is gonna replace a coil. She goes to Advance Auto in a small town and they read the code. Uh oh, not the cheapchina coil that I have replaced before, the misfire is cylinder 2 on the backside of the engine and you have to remove the intake to get to those coils. My daughter and her fiance are nearby and i walk them how to pull the coil out and put in the new NGK coil she bought from advance. (Yes i assumed it was a coil). They button everything back up big Flexy still has a bad misfire. Told wife i will have to drive out there tomorrow and fix it. Fast forward to this morning and we drive out to Farmville (60 miles away) and I go to work, confident we will be on the road in under an hour. Move some plugs around expecting to see the code move, nope stays on cylinder 2 regardless of which coil i put there. Pull the spark plug, it looks fine. 2 hours later, i decide to drive it home and work on it after i google and youtube how to diagnose this. Decided it was probably the fuel injector based on a bunch of facts I am leaving out of this post. Saw a Chris Fix video showing the test of an injectors impedence would probably confirm my suspicion. I tested the impedence of 2 injectors up front and then go for the injector on cylinder #2. Nada, no reading...what? Try it again, the sun is going down so i get the wife to hold a flashlight there and pull out the prongs to my mulitmeter....there is oil all over the prongs....what? Yes oil, as in 5w30. Look down in the connector, oil is pooled in there. Use several paper towels to get the oil mopped up and clean off the connectors, still no reading on the multimeter. Tomorrow I guess Im going to replace a fuel injector, but HOW IN THE WORLD DID OIL GET IN THEM? I realize this a direct injection car...but oil forced its way back up into fuel injector? No oil dripped into the connector because the top of the connector was dry. Do i have bigger problems than a failed injector? Thanks for reading my story, not sure I want to know what Big Flexy has in store for me next weekend.
