Steve, it's all in good fun -- had you been down the path I have with the shoddy workmanship of under-engineered F150 parts and Holier-than-Thou Ford dealerships, I'm sure you'd give the same due credit.
Alas, I'm here for INTELLIGENT responses only, thank you.
BLUEGRASS: Thank you, Sir -- without making my first post into a novel, I DID wish it to be understood that the obvious (air? Fuel? Spark?) questions were confirmed in working order.
Based on your advice, I swapped the TFI and that was not the issue. The TB was cleaned in the winter whilst changing the TPS (that was mounted UNDER the TB) and whether or not associated, there was coolant leaking through -- I disconnected the 3/8" in/out coolant lines to prevent my new TPS from getting contaminated.
As for DTC 538, I was under the impression that it had something to do with the KOER test that checked to see how the EEC could relate fuel management to RPM changes... (too many books say too many things)
Otherwise, there is a hall effect sensor in the distributor that apparently causes this 538 code -- and we ALL know how much fun it is to take Ford's distributor apart... I was hopeful that this would have been a given first-response "cure"...
Update: the engine never stalls when cold, and while doing a break-torque when the engine is hot, it NEVER stalls... (never could get the tires to spin, either!) And again, the temperature guage is slightly higher than the norm. I WILL investigate the fuel pressure while under load as soon as possible. Is there a strainer on the in-tank fuel pump I wonder?
BTW, Bluegrass, what's your Lincoln pulling in the 1/4 mile?
