Car Forum / Subaru Cars / November 2007P0108/rough idle error code after fishtailing and spinning on the highway
This morning I had a a P0108 error code (Manifold Absolute Pressure/ Barometric Pressure Circuit High Input) come on after I lost control of my 2000 Legacy GT 5speed on the highway - fishtailed about 4 times and then did a complete 360 before coming to a stop (deer jumped about a quarter second in front of me at 65 mph). Now the car has a really rough, low RPM idle but is fine at speed. Does anyone know what the cause of this could be? -Adam Peacock adam@thepeacock.net > This morning I had a a P0108 error code (Manifold Absolute Pressure/ > Barometric Pressure Circuit High Input) come on after I lost control [quoted text clipped - 3 lines] > rough, low RPM idle but is fine at speed. Does anyone know what the > cause of this could be? You scared the hell out of it. Look for a vacuum line that may have come off. Intake, throttle body would be a good starting point. > This morning I had a a P0108 error code (Manifold Absolute Pressure/ > Barometric Pressure Circuit High Input) come on after I lost control [quoted text clipped - 6 lines] > -Adam Peacock > adam@thepeacock.net > Look for a vacuum line that may have come off.

I would also just clear the code and see if it returns. I suspect it will, the rough idle seems to point to a real issue, but sometimes clearing the ECU will work miracles.

I have cleared misfire codes (from my wife leaving the gas cap off) and the car smooths out. Just wondering what caused your wife to misfire and what kind of gas cap she has... i might one day need one for mine... ;) >>>Look for a vacuum line that may have come off.

Since only their creator can understand them and they seem to communicate by telepathy or something, I doubt anyone will ever figure out why they misfire. And when they do, the response is certainly a code of some kind; and they don't need any kind of cap to do it... > Just wondering what caused your wife to misfire and what kind of gas cap > she has... i might one day need one for mine... ;) [quoted text clipped - 23 lines] >> misfire codes (from my wife leaving the gas cap off) and the car smooths >> out. > Wives misfire constantly.

Mine misfires all the time. My Subaru runs fine though. > > Wives misfire constantly.

Of course, it will also clear your settings on the radio. >A lot of times you can clear the codes by disconnecting the negative >battery cable for a couple of minutes.

I bought the nicer one at $100 and it's come in a lot more handy than I'd ever think. Or you can take the car to auto zone when they're not busy. They'll scan and read the codes... but i dunno if they'll erase em though. -- Todd H. 2001 Legacy Outback Wagon, 2.5L H-4 Chicago, Illinois USA >> Wives misfire constantly.
