Little back story. My 35 year old engine control wiring harness was toast so I went with a Painless harness. It does away with a lot of the superfluous crap that's not needed. https://www.summitracing.com/parts/prf-60510?srsltid=AfmBOorr5PZ4VJ8SF2f_Vs_Em8YVra1KZ_I_5ggDCRO9m5cg-SC2KPCr_pE So...

I have a front seal leak (just a drip really) on my newly rebuilt '93 5.0. Question: Am I missing dowel pins that need to align the timing cover so the crank is centered in the TC bore? This pic is from teardown and I don't remember any dowel pins. This is after I pulled the balancer to try...

'93 AOD. What's the proper way to check trans fluid to get an accurate reading? I'm running straight Mercon V. When I floor it, the car shifts pretty hard going into 2nd gear. Enough to 'chirp' the tires.

Pulled codes on '93 5.0 and got 81,82,85,84. It cycled back and displayed the same codes again (as it should). Then, I got the 10 seperator code and the continuous memory codes came up. I pulled a 33 (EGR) and 66 (MAF). It cycled back and displayed the 33 again (as it should) but the 66...

OK, the snowflakes are a bit much. Pretty distracting! With that being said.......I need to replace the entire ECU wiring harness. '93 5.0. The 30 year old original just isn't cutting it! I need to replace virtually every wire and connector off the 60 pin connector. Painless is quality and...

I pulled KOER codes on '93 Mustang 5.0 and the first number that pops up is the cylinder identification code. It's a 6. Shouldn't it be an 8? This is with the basic Innova 3145 OBD1 digital code reader. Inquiring minds want to know.

Better yet is there a link to all the tutorials he's written?

Trying to figure out what's going on here. '93 5.0/AOD. It fires right up but, I have to feather the throttle a lot to keep it running. It doesn't smooth out until probably 3K rpm (don't know for sure cuz I have no tach right now). However, once temp reaches 195* and the thermostat opens, I...

On my '93 5.0 I have a code 66 - MAF below minimum voltage. There's probably a write-up on here somewhere on how to measure MAF voltage. Would someone point me to that please?

Like the title says, it's leaking from the bottom of the rear cover plate. I already pulled the water pump. It's a new Ford Racing M-8501, non reverse rotation cuz I have an early timing cover on the motor. I installed a FelPro gasket on the rear cover and it leaks. Would I be better off...

I need to make a decision for my '54 project. I loved the sound my donor '93 LX had! Stock 5.0 motor with Magnaflows. It sounded healthy and mellow but not droney (is that a word?) Don't know what model number the mufflers were but they were rather long. It also had the full cat system on...

It's a brand new Stewart Warner Wings electric oil pressure gauge. When I turn the key to 'on' it stays at zero but as soon as I hit 'start' the gauge pegs at 80 psi and stays there. However, after I start it once, then shut it off, if I turn it to 'on' again then it pegs at 80. If I let it sit...

Set base timing at 13* BTDC with SPOUT out and with SPOUT back in it runs about 22*. Does that sound right? It also has a lopey sound to it but it's the factory roller cam. Open headers if that makes a difference. Also, what's oil pressure supposed to be at? My SW electric gauge pegs at...

If it's not one thing, it's another! Now I can't get the motor to start. '93 5.0 from a Mustang. Basically, a fresh rebuild. I've got fuel (shoots out when I depress the schrader valve) and spark (good spark outta the plug wires). At TDC the timing mark is where it's supposed to be and the...

I wanted to prime the engine before startup by spinning the oil pump with a drill. Pulled the distributor, attached a 1/4" hex driver to my long drill extension using the 2 small set screws, chucked it in my drill and went to town. After priming, I pulled it out and found 1 set screw missing...

Mine slides in and out easily. If I turn the lower intake upside down, the grommet will fall right out. Shouldn't it be tighter than that?

When turning the key to 'ON' the fuel pump should run for a couple of seconds, then shut off....correct? That doesn't happen. The only way to make it work is to jump power to pin #87 (Bosch style relay) and it'll run constantly. Doesn't build up fuel pressure 'cause there's no fuel in the...

Just did a tranny service on my '93 AOD (filter/gasket/chrome pan). Got about 6 quarts in and I hear it leaking underneath. It's pouring out between the tailshaft and inside of seal! The front end is raised up. Tell me it's just because I have the driveshaft removed.....please! I'm not a...

Like the title says. Rubber, cork, RTV or something else? All insight or opinions are appreciated!

I have an aftermarket throttle cable on my 5.0. Factory cable bracket (slightly modified) that also utilizes the AOD tv cable. The aftemarket cable came with a throttle return spring. Is the big spring that's wrapped around the shaft that controls the butterfly valve enough of a return spring...
