Was on my way to lunch and the car started bucking hard and then died at an intersection. Pulled codes via torque and all that showed up was cylinder 3 misfire. Plugs are Motorcraft Sp534s and have 3k on them. Always run 93 octane on my 4 plus tune. What are the cylinder numbers for the front and rear bank. Will pull plugs after class. Also before this happened the ac got warm and its only 85 degrees and I was just crusing real slow like a grandma.

Is there a strong gas smell?  Could be an injector stuck on...

No gas smell at all, I have noticed at idle that the car would have some white smoke or condensation for the last month or so in the morning even when it was 70 degrees outside. I also noticed that torque is showing the coolant temp to be 145 degrees, and the coolant temp gauge is below it snormal operating area, and prior to this happening the gauge was in the middle between c and h. The factory 02's are reading an A/F ratio of 9.8 to 1 and calling for 14.7.

9.8 to 1 is ridiculously rich at idle.  That would seem to indicate a lot of gas is present...

Weird on the coolant gauge though.  Are you saying it's at 145 right now?  The car doesn't run correct?  I'm trying to figure out if it just cooled down to that temp or if you are running it and it won't warm up?

Sorry I got it started but it runs real rough. I drove it slow back to school. Max temp was 145 degrees. Its 85 out right now, and it always runs around 179 to 189 driving the same way. Where is cylinder number 3?

Could this be from keeping the obdlink plugged in?

Does it light up dash warnings when started?

Great question.  I searched but only found it for the F150 - not sure what the "front" would be in the Transverse application.  I will keep looking...perhaps someone else will chime in that knows.

I don't see how.  I still think it sounds like an injector given the insane A/F ratio and other symptoms he's got.

That ratio is crazy...first call would be to tuner...then back to stock to see if you can duplicate.

As you stand in front of the engine bay I 'think' it's the back right one (drivers side farthest away from the front).  Don't hold me to that though.  If it isn't that one then it should be the closest left standing in front of the car and facing it.

Hope it's closest left...as the back right is hardest to get to I think.
