Razzmatazz

So I have exhausted every search function on every pathfinder forum and here we are. Any ideas? '02 3.5 pathy with 295,xxx on it Was driving through town one day when it just died at a red light. Only way to keep it going was feathering the gas on startup and left foot braking to get home, if I let off the gas it died. Did some research, figured it was the IACV. Ordered one of those. I then put a zip tie over the throttle stop screw, just to use as a spacer to keep the throttle open a bit so that it would idle without me being in the drivers seat. Got one whiff of a weird smell I hadn't had before (no smoke from the steering column/ecu area) and shut it off. Replaced the IACV with a hitachi OEM unit, pulled the ecu apart to check if that IC17 chip had been fried by the failed iacv, or if there were any other signs of damage. Nothing, and i mean nothing, looks mint. Changed the TPS next to another OEM Hitachi unit, made sure to install it with exactly the same orientation as the original (it was a hitachi and looked factory). Truck still won't idle. Starts up but immediately falls on its face and dies without throttle. Sounds great with some throttle though, real smooth and steady. If I unplug the MAF while its running it dies so that leads me to believe that's working. When I plug in my scantool to the obd2 I don't get any codes either. I can't do the idle relearn procedure OR the Tps relearn if the truck won't stay running without the throttle open. Also really havent been able to come up with a good tps adjustment how-to/diagnostic. If anyone has one that would be the next thing I'd like to check more thoroughly.
