NEED HELP! Codes:P0171, P0174, P0304, Symptoms inside

[WormGod]

THAT is where I think your problems lie. I would be really looking into the wiring as it sounds like it is "imitating" the symptoms of a bad MAF.

Indeed, it all came down to wiring. Squeezing on the TPS line/wires would oscillate the idle rpms. Plus, it threw a TPS CEL code, so that was GOOD. So, I knew where to look....

Now, dig this....

Last night, I tore it all down again. Pulled all vacuum lines, pulled all wiring harnesses, and removed the S/C. It appears I have found the villain playing castaway in my engine. Under the S/C plenum I found a family of well-done field mice and a handful of medium-rare babies. ALL wiring that was anywhere near that area was chewed right down to the copper. I am surprised my problems weren't 10X as bad as they are now. Luckily, it doesn't appear that they chewed on any vacuum line, gaskets, etc.

I shop vacc'd out what was left of the bastards (sorry, I had cell phone pics but they didn't come out, heh) and cut all new wiring. Started soldering my wires again and hoped to have it all done but sadly, I couldn't find my shrink tubing, so work came to a halt.

While on this subject, the stock wiring is absolutely HORRIBLE. Cheapest damned wire I have ever worked with. Thin, brittle, and not easy to work with. I get this crap done (and hope it solves my plethora of dodgy problems) and then it's off to solving the trannie/mode switch/clunk. *sigh*

Little bastard mice!! They have caused me a lot of grief too. I'm afraid to start up the 928 each spring for fear of where they've built a nest and will the thing catch on fire once the engine warms up. I've had them in the VX, in my wife's old car, in the Mini Cooper... EVERYWHERE.

Yeah, in the past I would find half-eaten hickory nuts on top my Supercharger!

Had baby red squirrels in my heater (blower) fan.

Lost my underhood insulation to mama squirrel to build said nest in (blower) fan.

I've had good success since by periodically driving it and moving it to different spots in the yard/driveway. Seems to keep the critters off balance!
