    Help and Maintenance Information

    With many regrets, our original-owner 1992 black on black SHO, which was passed along to my son a few years ago, has moved on to a new owner/caretaker, and we are SHOless. I've always enjoyed contributing here. I'd like to leave you with links to the collection of random Gen 1 and Gen 2 repair...

    SHO repair north of NYC?

    Is there anybody who is a knowledgeable SHO mechanic north of New York City in the Westchester County area or close by? Son has our SHO up there with a fuel related no-start condition. It's been sitting in the lot of a supposedly reputable shop run by a mechanic who supposedly owned a SHO, and...

    Mustang, Ranger 1991 Crank Sensor?

    I wish SHO Source would come up with a kit to tap and reroute weep hole coolant away from the CPS. I'd do it myself if I had any time, so that's why I'm picking on those guys :-) .

    Got a big job in front of me

    Not intending to throw cold water on your plans in any way, but rather to share a simple fact about the factory configuration, the alternator that came on your '92 is one of the finest made. Model years with the Ford made alternator, less so.

    Is it true u need to pull spout plug to set timing?

    Or a ground wire from the strut tower ground stud to either one of the lower DIS mounting screws.

    Cam seal

    Put a thin coat of RTV around the perimeter of the seal or else it can leak at the seam in the housing (even the rubber coated seals). Use grease on the lips of the seal. You have to keep the seal absolutely straight as it goes on, and that is very difficult. I slowly tap them in place with a...

    Coolant Pipe

    Attempting to replace the front part of the water pump, leaving the housing in place, frequently results in a leak because the tiny seal on the back of the housing slips out of place. This has been discussed in a number of threads over the years. Perhaps if the housing is RTV'ed in place so it...

    RockAuto Crankshaft sensor availability! Maybe???

    ebay is the best bet. It took months of watching, but I snagged a NOS Motorcraft from a seller out of Puerto Rico of all places. Cost me a fortune, but still less than a day of my time scrounging at a junkyard. A Wells sensor lasted 100K miles before it started acting up when hot, possibly...

    Exhaust upgrade on a stock 1993mod

    If you're on a budget, the Thrush 17712 with the factory resonator sounds good, but not loud. If you cut the stock muffler off leaving its inlet welded to the tail pipe, it makes a perfect size bushing to fit the Thrush muffler. Use with Walker 41420 tips. On the right side, reuse the factory...

    Atx to mtx conversion wont rev past 5k

    Since you've ruled out many logical things, that leaves only out of the box things to check. I like rubydist's thought of the timing belt being off a tooth or so, or the cam timing being otherwise off. You could have an exhaust system restriction. You could have a strange intake restriction...

    I have the SHO ghost smh

    You can check exhaust system back pressure with a gauge that taps into the 02 sensor bung. Are your fuel injectors the correct ones? We're running Denso O2 sensors, FWIW.

    New problem

    The fan runs when the either the coolant temperature is high or the A/C is on, whenever the car is moving at less than 50 mph. If it's working in those conditions, I would not worry over what happens when the ignition key is cycled.

    I have the SHO ghost smh

    Since you've hit most everything else, perhaps an exhaust system restriction?

    92 mtx backfiring, no start

    If I may, the SHO camshaft sensor is called the Cylinder Indentification Sensor, or CID. The crankshaft sensor is called the Profile Ignition Pickup, or PIP, by Ford. Source: The Ford Parts and Service Division Technical Training, Engine Operations - SHO 3.0L , published in 1988 (often...

    Hard Start When Car is Warm

    I suggest getting a Lithium Ion jump pack, aka jump starter, to carry in the car for peace of mind until you get this sorted out. The cam sensor is relatively easy to change out, so it's a good place to start.

    CPS Bolts

    Me too, which is why I was thinking button head torx. However, button head stainless is available in hex drive too, if one prefers that to torx...

    CPS Bolts

    Thanks for posting the thread size. How about a torx drive button head instead? https://www.amazon.com/Stainless-Button-Socket-Screws-Metric/dp/B07NXFZX5T/ref=sr_1_3?keywords=M4-0.7+x+10mm+torx&qid=1563501024&s=hi&sr=1-3

    I cannot find a CKS. Anyone know where to find one?

    There is a good explanation of the DIS and the CPS operation in the SHO Engine Book. It is a hall effect device, which is the most common type. I don't have a SHO motor to experiment with fit, but it makes me wonder if another part number could be adapted. For example, in physical appearance...
