Been doing stuff, just now finally got off my arse to post something. The new motor is in, I cranked it up and it ran... For about 45 seconds. Then it shut down. I re-started it, ran for about 45 seconds. Rinse and repeat. While it was running, it didn't knock, blow up or toss giblets across the room. It did run rich as hell, stink up the garage and cause me to go outside to breathe. Not oil smoke, just raw gas...

I pulled error codes with my handy-dandy Autozone (The Harbor Freight of autoparts!) scanner and got all the same ones I got BEFORE I rebuilt the engine... Weird... James (Earl to the Team Slotus Faithful) suggested I try disconnecting one sensor at a time and re-starting it to see what happened. I did that, and mostly noted "No change". Pulled the plug on the TPS, nope. Pulled the plug on the IAC, nope. Intake Air Sensor, nope. Finally got back to the Manifold Absolute Pressure (MAP) sensor. Pulled the wire off it. Cranked it up, and it idled. Still waaa-aay to rich but it kept running. Thinking I had found something, I bought and installed a new MAP. Cranked right up, ran 45 seconds, shut down. WHAT THE HELL!?!?!?!?

I started to wonder if the problem was the CPU, or as Ford calls it, the PCM. Rob, another Ford-racer buddy of mine, had suggested that to me earlier, that the old Speed/Density PCM wasn't able to cope with the increased intake volume of the stroker. I also remember getting those error codes and thinking the idle mix was too rich even way back when. Seems like we struggled to get the idle right from day one... Hmmm.... Maybe that PCM wasn't working right all along, just running on "Limp Home" mode????

Sooooo.... I'm now in the process of converting from the old (1992) PCM with speed density and MAP to a "New-Old-Stock" Ford PCM for a Mustang GT with Mass Airflow type design that James/Earl was able to procure for me at a nice discount price. I don't know if me and Bubba can do this kind of eleck-tronick wizardry, but we're gonna have a go at it. If you see a blue-ish glow on the southern horizon one night, you'll know the answer was "No, they can't do that kind of wizardry." Send donations to TWWTFM...

OK, gonna go for more coffee now... Stay tuned...
Peace, Love and "Limpin' Home"-
