Check Engine Lite!!! Please Help!!!
I recently purchased a 2001 Ford Taurus SEL at a local auto auction. After the auction, while driving the vehicle on the auction lot, the check engine lite came on and the engine started missing.
Thier techs pulled the code and found "#4 cylinder missfire". They couldn't find anything and thought maybe a plug wire was loose. (They said that some people would loosen wires and such to make the car run rough hoping to gain an advantage during the sale) They reset the code and everthing seemed fine on the test drive.
We picked the car up two days later and the exact same thing occured again.
Engine lite on constant, car seems to run fine. Lite begins to blink and car stumbles.
Code still read "#4 cylinder missfire". Local garage diagnosed as the intake manifold leaking at the #4 cylnider. I authorized $317.00 for the repair and it did not work. They now say they don't know what the problem is.
The car has new plugs, wires and coil.
I have it at a local Ford dealer hoping the "experts" can fix it.
Anyone have advice?? Thank you.
