    Any electronics gurus here? Building a CD changer emulator for Fords.

    What I want to do is make a changer emulator that plays MP3 files from an SD card. The control protocol is Ford ACP, based on RS-485 serial. Audio is fed to the head unit as stereo analog. Ford ACP was used circa 1996-2004 or later. Some people have made things to plug in which control their...

    It it possible to get the magazine out of a F87F-18C830-AA CD changer without having it powered up?

    How rare are 3.55 gears with a 5.0?

    I'm thinking swapping 3.55 gears in place of 3.73's should up MPG a bit. But I've yet to find any Mountaineer or Explorer with a 5.0 that has anything other than 3.73. If 3.55 was a 2WD only option, that'll make the swap a bit difficult for AWD. I have equipment and software to program tire...

    Rear axle swap, 1997 to early 1998?

    I'm getting a 1997 Mountaineer with a running 302 and bad transmission, as a potential parts donor. $500 with nice aluminum wheels and a set of tires with only 800 miles on them, plus it just had all new brakes and rotors front and rear before low/reverse went out in the transmission. The rear...

    How to test the 5.0 V8 coil packs?

    I've searched the web for hours but all I get is information on newer ones or for engines that are other than the 302 5.0 V8.

    Testing for defective EEC V computer?

    Is there a DIY way to test if an EEC IV computer is defective? All the parts stores around here have gotten rid of their PCM testing equipment. I have a 2002 Sport Trac with a 1998 Mountaineer 5.0 drivetrain. It suddenly quit running while at idle. I changed the crank sensor and it would run...

    Running fine then it quit

    02 Sport Trac with 1998 V8 Mountaineer drivetrain swap. Went to Subway last night. Got in the truck to come home, started it up and after about 5 seconds it quit. Checked all the fuses, they're fine. Could smell it's getting gas but zero evidence that it's getting spark. Recently it's had new...

    Adjusting rod for outside front door handle?

    1998 Mountaineer right front door will not open from outside but will open from inside. There's no problem with the electric lock or door ajar. Just the outside handle. I have the panel off the door and I can feel the bottom of the rod to the outside handle is threaded, goes through a plastic...

    What's missing on the fuel vent hose?

    Found something else the idiot who did my 2002 Sport Trac V8 swap screwed up. Take a look at this photo under the left bed side. A hose to nowhere. Both it and the small pipe that goes into the fill neck lead back to the fuel vapor stuff above the spare tire. It had become difficult to get gas...

    Random 5.0 misfiring in 1998 Mountaineer.

    Part of the time it runs perfectly. Part of the time it's randomly misfiring and surging and getting bad gas mileage. What's been changed so far. Injectors, plugs, wires, IAC, EGR valve and pipe (had a crack), EGR pressure sensor, TPS, coils (just put new Motorcraft ones on), timing chain and...

    2002 Fuel reset light, can't get it to reset.

    The fuel reset light is on and the truck won't start. I checked the cutoff switch by the right side kick panel, the button was NOT up. So I whacked it good with a screwdriver handle and it popped up. Pushed it back down - the Fuel Reset light is still on, still won't start. Co-incidentally I...

    2002 keeps frying heater fan relays.

    The contact for the heater fan relay closest to the left/outside of the power block under the hood is brown from heat and the contact in the block also looks burned. I've scraped it clean and installed the highest amp (30) relay I can find but about every month or so it fries the replacement...

    Testing EGR pressure sensor?

    How do I tell if the sensor is bad? Changing the EGR valve on a 1998 5.0 and found a small crack in the pipe, ordered two pipes from Stylin Trucks (second one 'cause I'm sure the valve needs replaced on another truck). Lots of black soot in the pipe, found the crack in the accordion section...

    Wrench size for 5.0 EGR tube?

    What size wrench is the nut at the bottom end of the EGR tube supposed to be? 1-1/8" sort of fits and by using two different open end wrenches and flipping them over I can very slowly get it unscrewed. I've been trying to find a 1-1/8" crowfoot wrench without any luck unless I want to buy...

    Too much fuel being injected in 1998 5.0

    What causes the PCM to decide there's not enough fuel being injected and respond by opening the flood gates? I've replaced the injectors, pressure regulator, fuel pump, filter, throttle position sensor, oxygen sensors, catalytic converters, plugs, wires, coils and cleaned the MAF, throttle body...

    Anyone in Chattanooga area know Ford EFI?

    Going to be there all next week for the Hudson meet at Chattanooga choo choo hotel. I put new converters, new o2 sensors, new tps, new injectors, new coils, spark plugs, plug wires. It still keeps insisting the upstream sensors are bad then pours gas through it so it runs crappy and gets 9...

    Front ABS sensors 2WD vs 4WD vs AWD?

    Is there any difference in the front ABS sensors on 2 wheel drive, 4 wheel drive and All wheel drive (Explorer Mountaineer)? Oreilly's site lists different front sensors for 2WD and 4WD but when looking them up for a 98 Mountaineer V8 it lists ones for 4WD when there was no such thing, the...

    V8 swap acceleration switch errors

    Error codes C1102 C1230 C1237 What do I need to look for to fix those? The speedometer works fine. The rear axle sensor was changed in the donor vehicle shortly before the swap, attempting to get its ABS to work. I installed a complete new ABS unit for a 1998 Explorer/Mountaineer. No...

    Downstream O2 sensor damaged by running too rich?

    1998 Mountaineer V8. Changed bank 1 downstream sensor that was damaged. Ran fine until both upstream sensors completely quit so it would crank the fuel trim up to full rich. So I replaced the other three sensors. Now it's doing both 0171 and 0175. Bank 1 alternating between too lean and too...

    302 head casting # for 1998 Mountaineer?

    Timing chain in my 98 Mountaineer decided today was its final day, fortunately right after it fired up, not while running down the road. Started up *bang* and died. Will most likely have at least one bent valve and-or pushrod. I want to get rebuilt heads on the way before I take things apart...

    7 P-codes, running poorly. 1998 V8.

    What are the part numbers for the PCV hose(s) on a 1998 V8 Mountaineer? Ford can't get them. When I changed the injectors and installed a new PCV valve, I noticed the hose looked a bit iffy. The valve wasn't in its hole in the intake but I chalked that up to the idjit I had do the V8 swap into...

    Anyone have an NGS system?

    New Generation Star. I'm thinking one of those may be the only way I'll ever get the ABS service bleed done on my V8 2002 Sport Trac so the ABS will quit disabling itself since I installed the new unit. I'm in Weiser Idaho and there doesn't seem to be anyone else on this forum between the...

    Vector art for Sport Trac and 5.0 logos?

    I have a Sport Trac with a 5.0, AWD and a CNC milling machine**. The decorative intake cover plate with just the 5.0 on it is a bit boring. I have an idea to mill a new plate with the 5.0 shrunk and the same Sport Trac as is on the tailgate above the 5.0. Easiest method will likely be to...

    Heater pipe removal on 1998 5.0?

    How do I remove the metal heater pipes from a 1998 5.0? Is that a swivel nut fitting at the front? If not it looks like the engine would have to be out and the whole intake off to give the pipes room to swing around and round to unscrew. I ask because the numbskull who did the swap from a 98...
