    Interior and Upholstery Air bag safety

    I have not seen info on this before here and a search is not bringing up anything. What has to be done to disarm the air bag system on Fox Mustangs before changing modules, sensors or the bag? Is disconnecting the battery enough? Are there capacitors that need to discharge before working on any...

    Digital Tuning Data Logging with EECIV????

    I am getting spoiled by OBD2 cars that give live readings even with a Wal-Mart code reader. Is there a way to hook up a laptop to read what info the EECIV is getting and sending? And I mean one still available, as the diagnostic port was for something from Ford. ;-) I suspect the air or water...

    Vacuum advance with two ports

    I helped tune up a 69 302 auto coupe that had two ports on the distributor’s vac advance. Which one should be hooked up to ported or manifold vacuum? And should the other be hooked up to a temp controlled, ported vacuum switch on the manifold? A Diagram would help. Thanks!

    Site glitch problem fixed. See sticky for further info

    I kept getting this error message this AM when I was supposed to be doing other things. As it periodically pops up since the last site upgrade, I am sharing the screen shot from the 24th with the same error.

    Paint and Body Undercoat or not? If not, then what?

    I have a car in the shop where I am using my checkbook to get the bodywork done. It is a low mile and very low rust car. As it is a budget restomod that’s I am going to drive, I am not going “frame off” (on a unibody-we need a better term). The top side looks great now. And I had planned on...

    Engine IAC question - normally open or closed with no power?

    Are 5.0 IAC valves normally open or closed? I just got a new Motor craft one from Rock Auto. Air blows through both holes without power. I've not checked one before, but I figured they were normally closed. This one is for the shelf while they are available, and I want to make sure it is right...

    Ford rim offset info, now with pictures.

    Is there a place I can find info on stock, 5 bolt Ford rims with different backspacing? I have a 75? Ford pick up box trailer. It has an 8” axle (probably off a car) installed upside down, under the springs. The vent was capped when I got it. I installed a vent on the top of the axle looked up...

    Suspension Alignment specs

    Please post for me what stock and spirited driving front alignment specs should be for a 91 LX, 5.0, factory pony 5 spoke rims, B springs, BBK C/C plates. I have had it with the closest tire place. They have a fancy machine and poor operators, and have made three vehicles pull or feel squirrely...

    Planing ahead for winter driving

    Until Dec 2020 when I had the wrong car out of storage, I had forgotten how bad (or exciting) a Fox 5.0 was with ice and snow. My 91 is a handful on wet roads, but even with A traction rated all season tires, it got stuck just moving over in the driveway that the G.Marquis had just driven out of...

    Rdub6’s F150 thread

    @Rdub6 I got your own thread started. Corvair rear glass is a bigger and different PITA than on an 02 F150. “I don’t know if I’m in the right spot..... but here goes. Im about to try to replace the seal around the rear glass in my ‘02 F150. They all seem to leak there, and mine has been for a...

    Electrical Premium stereo questions

    First question, on a 91 5.0 LX, does six speakers mean it came with the premium sound option? If so, is it likely they bypassed the stock amp when the po put in a pioneer deck? Is the factory amp of much use with a decent aftermarket deck? Will that amp be in the way when I switch around...

    Values for insurance, where to get?

    So besides Hagerty for vintage cars and KBB.com for cars going back to 1992, what other reliable sources of reference are there currently for fair market value on a 91 Mustang, and a 65 Olds Cutlass? The back story, when Nationwide tried to spin off the “collectibles” onto Hagerty, I got three...

    Drivetrain Checking for bent rear end

    I think I figured out how to check if an 8.8” rear is bent without the housing end tool @CarMichael Angelo borrowed from a friend. Before I tie in the algebra I have been helping my kids with, which tube or tubes is most likely to bend and are they going to twist or move forward or back? A...

    Progress Thread Resource thread request

    @jrichker and site janitors J, I have hassled your about a book, but have a more reasonable thought. Can we get a sticky list of the diagnostic and other write ups you have made? It’s a challenge to find posts by title. A search for “no start” comes back with no hits. Hidden resources are not as...

    Drivetrain Testing traction lock in the car

    I am having trouble finding specs on testing a 8.8 traction lock to see how worn the clutches are or are not. I think I remember reading about blocking the front wheels, jacking up one rear wheel and using a torque wrench to measure how hard it is to turn the wheel with the opposite one not...

    Progress Thread Goofy fuel gauge on slow progress

    After being here and owning my current Mustang for 10 years, I realize it would have been good to have a slow progress thread to keep track of what was done and ideas that need done. Searching through old posts works, but putting them in one spot would have been helpful. Pictures will follow if...

    Electrical 1991 5.0 battery size

    The catalogs call for a group 58 battery in a 91 5.0, but the tray I have has room for a longer battery. It clamps side to side fine, but there is approximately two inches of space front to rear. Was there originally a bigger battery specified (like an old 24F?) , or did somebody put in a...

    Drivetrain New hanging idle problem

    On a 91 5.0 LX 5 speed, the idle speed has periodically staying up near 2000 rpm after The car has stopped. And it will stay with the high RPM idle each time I stop, until I turn the car off and restart it. Then it runs fine, with the idle staying up when the car is coasting, and dropping down...
