NATO Gods, please help me!

Well? did you fire it up yet? I would like to see a resolution to this.

Also - the "TC hiccup" is basically an occasional stumble at idle. My car does it once every 30-40 seconds or so, but sometimes doesn't do it at all. It happens to a lot of TC's. Yes it's fixable - IIRC it's a grounding issue with the PCM. Cleaning grounding points and upgrading the PCM ground wires with 10 gauge wire I believe will typically fix the issue. Jeff can chime in on that one - he's the expert. I have the stuff to upgrade my grounds, but I'm too lazy, and it's been too cold for me to bother with it.

I fixed 95 percent of my idle hickup by running a 10 ga wire directly from pins 40 and 60 on the PCM directly to the battery. I paralleled the original PCM ground with the extra wire. Also wired injector power feed directly to battery via a relay, and powered the FP directly to the batt via a relay to take some of the current load and electrical noise off the IRCM and VPWR circuit.

Sorry for the delay. I'm in the last semester of a whopping masters degree, so time isn't always a commodity I have.

I repaired the wire, and ran the truck. Still has the "hiccup." Tomorrow morning I will scan for codes and attempt a wiring upgrade...per Jeff's description.

Jeff, do you have a write up for that procedure? (I may need more detail than your post)

Sorry, no writeup.

ok I'll reply if I have any questions.

It's easy to do. The PCM is behind the passenger kick panel. Take the panel off and you will see it. 40 and 60 are at the ends of a couple rows of pins. I think they're labelled on the side of the connector on the pcm itself.

Jeff - did you use one wire on each (2 new wires) or a single wire for both (one new wire)?

Brian, I tapped into 40 and 60 within a few inches of the PCM connector with 12 ga wires, and connected those to 1 10 ga within a foot or so of the PCM connector. Ran that directly to the neg batt terminal with no connectors, etc in the wire run. Stock, PCM ground (40 and 60) go thru either 2 or 3 connectors before getting to the neg batt cable, and the original wires dont look that heavy of a gauge. FYI, 40 and 60 are internally connected inside the PCM right where the 60 pin connector connects to the circuit board.

Since our injectors all fire at once, and are low impedance peak and hold, the instantaneous inrush current pulled from the VPWR circuit (which is powered by the PCM power relay) when the PCM fires the injectors is 25 to 28 amps for a short time (I think around 100 microseconds or so). That has got to add a ton of electrical noise to the VPWR circuit which could find its way to the PCM.
