    I seriously messed up

    2004 Expy 4.6L. I removed my intake manifold to replace some bad gaskets. I diagrammed which hoses went where but now I've misplaced my diagram (probably threw it away in a fit of rage when cleaning up the garage). Is there some sort of diagram available that shows which lines go into the back...

    Intake Manifold Insulator

    2004 4.6l 162,100 miles. I'm replacing the intake manifold gaskets because of a slight leak. When I finally got to remove the intake I found broken plastic pieces. These came from the insulator box. The box crumbled when I removed it. My question is do I need this? What are alternatives to...

    AC Drain Tube

    I have an 04 expedition 4.6L. I have a wet passenger floor board. I dont have a sun roof. I cant find/see the ac drain tube. Does anyone have pictures and some instructions on clearing. I did a search on the forum and I have seen posts that explain it but pictures are no longer available.

    No crank

    The wiring diagram made all difference. Little yellow and blue wire was the problem.

    It wasnt overheating. I checked the oil for any signs of coolant and there wasnt any leak.

    No crank

    2004 4.6L. I replaced the PCM relay and it didnt make a difference. I checked ground wires but didnt do a voltage drop test. Thanks for the explanation of 87 and 30. I will see about that this evening.

    I'm unclear on what you mean by 87 and 30 terminal?

    No crank

    I was working on an coolant leak in the emtal line that runs to the rear. Took it for a long drive and the line is fixed but when I went back out the best day my expy won't crank. So I had the battery checked and it registered as bad. So I replaced the battery and still no luck. So I cleaned...

    Heater AC Control

    The valve appears to be working. If I zip tie it closed it stays cool. There is no noise like the blend door is trying to open or close.

    Heater AC Control

    When I use max ac there is a vacuum on the supply line. Regular ac there is no suction at all.

    Heater AC Control

    I have an 04 expedition. Max AC works well and blows extremely cold. When I change to any other setting besides Max AC it blows warm to hot air into the cabin (both front and rear). The temperature dial also does nothing to change the air temperature even on max AC, always cold. Is it a...

    Backfire and then all good

    Backfire is gone and no more codes. I'm not concerned about the wires so much but the rubber lines for the AC pressing against the O2 sensor.

    Backfire and then all good

    Looks like the previous owner put a custom exhaust on the expy. What that did was change the location of the O2 sensor. Once the exhaust was installed there wasn't enough room for the O2 sensor and the firewall/body. I'm guessing he just decided to plug the hole and snip the wires. I...

    Backfire and then all good

    Thanks for all the replies. I went to test the O2 sensor and found the wiring harness was cut and no O2 sensor. Fixed the harness and a new O2 sensor has been installed. No more codes. My main concern is that the O2 sensor is pressing against one of the ac lines going to the rear ac. Should...

    Backfire and then all good

    I hooked up my reader and its showing 0.0000V reading for my O2 sensor in both the freeze frame and the live data. Doesn't matter how I rev the engine, the O2 sensor still reads 0.0000V.

    Backfire and then all good

    I want to be clear so if the reading stays .1V then its a bad O2 sensor?

    Backfire and then all good

    I cleared the codes last night and drove around and the only code that came back was the P2195. I looked at the live data and the freeze frame and it looks to be in a lean state. I've never tried to "Wake up" an O2 sensor. Can you tell me how to do this?

    Backfire and then all good

    The wiring diagram was a huge help. No power to EGR or Evap purge solenoid. Rechecked fuse and that was good. Unraveled the wiring harness going into the fuse box and found the red/yellow wire was cut. Looks like the prior owner was splicing into the wires for an aftermarket radio or...
