  1. 3L MTX vs ATX differences?

    3.0L V6
    When searching for salvage motors are the 3L's for the automatic different than the 3L's for the manuals? How are they different? Is there a trans bushing or something that's needed for the auto? The Fusion motors swap into either. I've swapped both so I'm curious why they list differently...

    I have a 07 Fusion motor in there so it doesn't have a water pump tensioner either. It was the serpentine belt tensioner pulley and idler pulley that were worn. ;)

    Evil car is still being evil.... The belt started to shred yesterday when I floored it to get out in busy traffic. I pulled the tensioner and idler. Both are a bit noisy so I'm going to replace the pulleys. Autozone gave me a pulley for the tensioner but when you bolt it down it won't spin...

    3.0L V6
    So you are saying there are 5 cat converters on this car then? I figured the rounded bulge after the y pipe had to be a resonator since there were already a cat and a precat (exhaust manifold) in each section of piping leading up to the motor. On the Contour/Cougar cars that is a...

    3.0L V6
    No check engine lights now for about 50 miles. Stacking those foulers did the trick. I did have another issue pop up. The gas gauge apparently doesn't go below 1/4 of a tank so I ran out of gas and had to push the car off the road. I pulled the pump last night and cleaned the sender...

    Precats usually get about $10-15 each at the recycling centers around here. Main cats will get you a bit more.

    3.0L V6
    I gutted both pre-cats this past weekend. The car drives 100% better. It doesn't feel like a pig down low any more. I no longer get any random misfires. I did have an issue with one of my COP units which I had to track down last night. The cat must have fried one of the COP units. I...
  8. Advice - pre-cat replacement - Catalytic Converter

    3.0L V6
    I did some more digging and found this excerpt: If the signal from the downstream oxygen sensor starts to mirror that from the upstream oxygen sensor(s), it means converter efficiency has dropped off and the converter isn't cleaning up the pollutants in the exhaust. If converter efficiency...

    3.0L V6
    Did you note how dead b1s2 is? Graph it. Its flat nearly the entire time. Popped a misfire on cylinder3 today and still have p0431. This is a fusion motor which was just swapped in. I bought the car with a bad motor. Old cop units were giving random misfires and horrible idle. Both lower...
  10. Engine Oil Pan Gasket & Front Crank Seal?

    3.0L V6
    The front seal isn't bad to replace. It should only take about an hour if you have a crank pulley removal tool. I swapped it on a Mazda 6 a few weeks ago.
  11. Advice - pre-cat replacement - Catalytic Converter

    3.0L V6
    I realize the upper O2's are for air/fuel monitoring since they are before the precats. The lowers monitor the catalytic effieciency. The problem is that the rear lower O2 which monitors the rear cat is not moving very much if at all when I'm monitoring it. All others are fine. The rear is...

    3.0L V6
    I added the graphs I wanted and turned logging on. I emailed the log file to myself but the files didn't have any of the graph data just some random accelerometer data. I didn't realize the logging variables are added under the settings menu. I'll add the correct sensors and then log on the...
  13. More weird isht... Bad BT odb2 dongle?

    3.0L V6
    Last night I was able to remove the OBD2 connector from the holder under the dash and move it out of the way so I wouldn't kick it. Works great.

    Do you happen to know if paying for the Torque Pro version is worth the upgrade? Does it unlock more sensor readings?
  15. More weird isht... Bad BT odb2 dongle?

    3.0L V6
    I hate how the dongle is right in the center under the dash I almost hit it with my foot when putting my foot on the brake which could do some damage. On other cars I've worked on it's on the side. Of course, my BT adapter isn't tiny by any means and I know there are smaller ones out there...
