I had seen the document listed here, but no one really had any confidence that it would solve the problem. However, in the past no one could really explain why that switch going bad would cause the problem or had any experience swapping it out or knew how/why it would change anything. I'm curious why neither of the dealer's even looked at this as an option when it was obvious that the IAC valve wasn't to blame any longer. I'll give it a shot. Thanks!!!

Hello all...I'm in desperate search of answers and are hoping someone here might be able to help. I've already searched here on this topic but only came across one thread that didn't really go very far, so I'm hoping that I maybe I was just not using the right key words... Here is the problem. I have a '99 Legacy Outback with around 95K miles. Just before selling the car, the original owner experienced rough running and massive loss of power, which was corrected by simply re-starting the car. The error code being thrown was 1507. A trip to a mechanic saw the valve cleaned out. The error came out soon again and the valve was replaced by the dealer. After I bought the car, it ran great for quite a while until the same problems came up. I took it to a different dealer who found a leak around the air cleaner due to a poorly fitting filter. The problem came up a few times again last winter, but at random times/conditions After nearly 7 months of error free driving the problem is back. The first time the engine flat out died with my daughter at the wheel and caused her to roll into another vehicle in a parking lot. Today the light came on while she was driving to school, with no symptoms other than the light. The light went off right after we had the codes read at AutoZone. I'm really at a loss as to how to fix this problem. One Indie mechanic and two dealership visits and the problem still persists...though not as often. No one can seem to solve it. I have thought of replacing the neutral switch, but lately the errors are popping up when the car is running in gear...not when the clutch is in. The IAC has been replaced about two years ago. I've replaced the air filter, fuel filter, and run a can of Seafoam through the induction system and fuel tank. I've talked at length with the guru's on LegacyOutback.net, read tons of stuff on NASIOC and any other forum/web site I can found. Nothing I've found yet has been very conclusive nor has anyone been able to fix the problem. Any insight or further suggestions? I really don't want my daughter driving a car that could crap out on her in the middle of a busy intersection...or worse, her high school parking lot, which is much more dangerous! Thanks

Hello! Another new guy and owner of a 99 Legacy Outback with a 5sp manual. I drove the car for nearly two years and have now passed the car on to my daughter for her first car. I like the car, especially when the weather is bad, and my daughter really likes it as well. Unfortunately we are having some problems with the car. A friend highly recommended this forum as a place to ask questions and hopefully get some advice....but that is for another thread.
