I have been having problems with my ford escape for amost two years now and Im ready to throw in the towel.. It started In the winter when id start the truck it wouldn't run on its own until it got to a certain temp you would have to sit in the freezing cold and hold the gas. In the spring I had trouble with it running period so I had to change the coils. all six. the plugs. the coolant temp sensor. the O2 sensors. 4 if I remember correctly. also the egr valve. which is a 3part system. and that still didn't fix the problem. I was told to change the coils again. so I did. still not fixed it starts better and will idle. but it has a miss. and the miss isn't always there it will come and go. In the past few months it has started a strong hesitation at different times while driving. I figured out that it ran better if I had shut off the overdrive til I got to a certain speed and then hit the button and let it shift into overdrive. after the vehicle had ran for approx 30 min it would run fine like new at times. Recently in the past month it has been using more oil. a qt a wk. and im smelling it burn. so yesterday I changed the valve cover gaskets intake gaskets and plugs. there was no oil leaking under the truck and a small amount burning on top of the motor once I got to where I could see. I expected to find oil on a spark plug explaining the running problems and oil burning smell. all the coils look fine except the front middle. there was nothing on the plug but the outside of the coil boot looked to have had oil on it and burned off. having no choice I put it all back together because I have to drive this vehicle. obviously the valve cover gasket and intake gasket were not my problem. There was no oil in any of the spark plug holes. although the plugs were shot from how its been running im sure. So I called the part store and the coils I bought had a lifetime warranty. so once again I get to tear my motor apart and change the coil/s MY QUESTION IS.. Does anyone know WHAT the real problem is. IF it is the coil. WHY do the coils keep going bad? Hopefully someone who knows can help me? please and thank you!
