P0170, P0505, P0120, P0403, P0141, P0130. I did some further checking last night and poking around on several Subaru forums about how to adjust the TPS found that there are some with 4 pin and some with three. if it has four it has an idle switch if three then it doesn't and "auto calibrates" on each engine start. Mine only has three. I disconnected the batt. Cleaned the MAF with special cleaner from AZ. and checked with an ohm meter between the middle pin and each of the outer pins. ( I never could find a diagram or labels to indicate which was pin 1. figured that the middle pin had to be #2) When I open the throttle plate the readings from the TPS were 0.75Kohm-3Kohm and the other was 5Kohm-1.5Kohm. I finally just more or less centered the TPS and put it all back together and is running with out the CEL coming on so far.

I was thinking hardware as in the ELM327 and the software being the application I'm running on the Android Platform, hadn't thought of the car not being able to send out the live data from the engine

Vehicle: 1996 Legacy Outback Scan tool: Bluetooth EML327 APP: Torque free the scan tool will read the logged codes but only gives me the engine coolant temp but no other live data with it reads from my 1996 GMC Jimmy. I looked on http://www.myscantool.com/vehicles.html#subaru. the Jimmy is VPW and the Subaru is ISO. is this a hardware issue or a software issue?

I've got an issue that sound some what related but it still has me confused. I have 1996 Legacy Outback with the 2.5l that I just bought two weeks ago, it had the classic "dead spot" in the tps behavior (nothing changes with the engine behavior with certain pedal positions) easy fix right? it had 5 codes present: TPS fault, MAF fault, EGR solinoid fault, upstream O2 and Downstream O2. I thought the easiest thing to fix was the TPS and it might help resolve the others. new tps and down the road we go... not!!! new tps and it ran pretty good til I cleared the codes to see which coeds would come back...and weird behavior here we come. while tring to drive at a constant 35 mph the engine will rev to about 3000 then cut out entirely and catch again about 1500-2000 and then repeat. it retained the TPS, up and down stream Codes and the EGR. I looked and somebody in the history of the Car had removed the EGR sulinoid and plugged all the vac lines to the EGR system, but I didn't think that the EGR would effect it that badly. I put the old TPS back in and it drove fairly decently, switched it out with the new one again and it went bonkers again. why would it be driveable with a bad tps and not with the new one? is there something else Im not seeing/understanding with the ECU system?
