Hi all. In a pinch. Currently stranded in Golden/Denver Colorado. Vehicle: 1998 Outback engine: ej251/25D hybrid Story: swapped a great running motor from my rusty '96 to this '98. In the process I put a NEW timing kit, NEW oem plugs, new oil pump, new clutch-kit/slave cyl., new oil pressure sender... ran beautifully all the way here from South Dakota, with many trips up and down the canyons from Hwy 119 to the Front Range. Two days ago, CEL came on and I stopped at an auto parts store. Got two misfire codes, and not having noticed any symptoms I cleared it. It coincided with using the a/c, so I moved the a/c harness off of/away from the spark plug wire. I figured something may have arced. No issues until trying to climb out of Denver up I-70 yesterday. CEL came on and flashed a few times. Pulled the car immediately to the side of the road and was turned off. Oil light did NOT come on. Symptoms came. Horribly shaky idle, no power. I checked all spark plugs (on the side of the road), and they were tight, and looked in okay condition. Idles like it is missing cylinders. While idling I pulled off/on all spark plug wires and injectors. No difference (except VERY minor idle-up for 1 second) with cylindees 1/3. Motor dies when 2/4 are pulled. Got towed to a local dealership and they were nice enough tp read the codes. P0261, and P0267 I believe this is Low/No voltage to cylinders 1 & 3 injectors. (In my frenzy I installed a new coil, and new spark plug wires) I took a volt meter to the yellow wire of each injector plug, with ignition switched to ON. 2 & 4 get 12v, 1 & 3 are dead. I tried directly wiring the yellow wires to the battery, and there was no difference in engine performance. Where/what should be my next step? Is it true that the injectors get constant power, but the ECU/ECM adjusts the pulse timing via internal grounds? I'll be looking at diagrams today to try and get this going...any suggestions will help. I'm supposed to be getting towed back up to Gilpin County where I'll have a garage to sit in. Thank you in advance for any suggestions! Greg -
I use a generic ELM327 v1.5 to read DTC codes from my 2003 Outback. Old Xoom tablet running Android 4.1.2 worked flawlessly. New phone running Android 5.1.1 would not stay connected. Fix is to set Protocol to ISO 9141-2. Using ScanMaster Lite v2.4. Protocol is set by starting the App. Tap the yellow engine logo in top left corner. Select Settings from pull down menu. Tap Communication->Protocol. Change from Automatic to ISO 9141-2 for the 2003 Outback 2.5l 4 cylinder. Back out to the main menu and connect to the vehicle. If that don't work, I'm out of helpfulness. I found the correct protocol to use at http://www.alpha-bid.com/media/Shared-Pics/OBD2_protocols.pdf Good luck to you, Mitch-
