The saga continues

Finally got my 99 Box to run. It appeared that my MAF failed. Ran fine with it unplugged, bought a new one from Pelican, installed it and it runs but like crap. It will idle for a few minutes then slowly die.
I disconnected my battery for a few minutes (reading more, I should have left it disconnected for longer).
I have the following codes and know what they are but do not know how to remedy them:
P0102
P0112
P0300
P0301
P0302
P0303
P1313
P1314
P1315
P1319
Recently replaced all plugs and coil packs, throttle body.
Please advise.

Simple, P0102 indicates a faulty MAF, so you either bought the wrong one or it is dead right out of the box, or its wiring is a problem. P0112 says the intake air sensor (in the MAF) is faulty or shorted. All the rest of the codes are misfire related.

Didn't have he P0101, have the P0102. I bought the correct MAF for a 99 2.5L base. I can only assume Pelican is not going to send out crap parts.

My post had a now corrected typo, it should have read P0102, which is a MAF low air flow code. So you still have the wrong MAF, a bad MAF and/or a MAF wiring issue. Porsche also released an updated MAF for the car, which requires a re-flash of the DME to work properly. You may have that sensor.

And every one sends out bad parts from time to time, Pelican included.

If I were you I'd start with a proper hard reset. Pull the negative cable off the battery and let it sit for at least 15 minutes. Then start it and see what you have. Let the car run for a bit and let it relearn idle and fuel trims. Then if you have codes, you'll know that it's one of JFPs suggestions. Start easy first.

Been there, done that. Left the battery disconnected (+ & - terminals) overnight. Runs worse. I guess I have to suck it up and take it in...
