Ford taurus 3 out of 6 misfires?
I have a 2001 ford taurus 24 valve (dual over head cam) (dohc). Cylinders 4,5,6 are misfiring (front 3 cylinders). I've replaced the coil pack, spark plug wires, spark plugs. Cleaned the egr and changed the o2 sensor (what the computer said was bad.) it said it was running rich last time i had it at autozone (2 days ago). I'm now looking at the fuel filter because on this model it has the fuel pressure regulater built into it… I don't know i just need a dorection in which to take action highly upset with this.
148,000 miles.
Then you should quit trying to play mechanic and get someone that knows how to diagnose motor problems. I'll bet you haven't even hooked up a scan tool that can read engine data and sensor voltages yet.
- What Ford Taurus bumpers (front or rear) would fit a 2003 ford Taurus ses? Looking around and seen someone with a 2004 front bumper on a 2003. Looks nice but curious if any other bumpers would fit? I installed new centennial edition headlights with Silver Star Ultra lights. here's what it looks like so far.
- 2002 ford taurus coolant bubbling out of coolant tank cap? Coolant is bubbling out of the tank cap on my taurus. The coolant is a bit over the fill to line. The coolant is the normal green color. I don't think it having a bit of extra coolant in the tank is doing this. The cap itself maybe? I just bought this car and it didn't do this until today.
