My car 99 Taurus, Vulcan engine is running rough. I keep getting a cylinder 5 misfire. Also included are lean fuel faults...I don't have the fault numbers as I type.
I have changed the coil block twice, spark plugs and wires. I notice that sometime especially when the car is cold, the engine runs smoothly. I think I have a dirty injector.
I have measured the DC resistance and the injector in question reads about the same as the others with 16 ohms. I am at a loss about how to replace this injector. They don't seem to be threaded in. Are they pressed in somehow???
How big of a job is to replace this guy. Fortunately it is in the front of the engine so that helps. Yes, I know I have to get the pressure off the rail, got an easy idea on that. Plan to trip the switch in the trunk...the roll over switch and then just run the engine until it stalls.
I have put about $40 of junk (Wally World) cleaners into the tank. No luck so far. Just bid on a can of bk44g or is it bg44k. anyway I doubt chemicals to solve the problem but who knows.
