I noticed yesterday as I started my Si to warm it up that after a few minutes of it warming up the idle will go from about 1000 RPM straight to 7-800RPM and the car feels like it's about to bog out. I thought the problem might be the fuel pressure being too high cause it was. Now it's between 55-60psi and I had that problem about 2 months ago and hadn't had it since I adjusted the fuel pressure until now. It's been mostly parked in my garage for that time, I've only driven it 2 times up the street and I warm it up at least 4 or 5 times a week. anyone have any ideas as too what could be causing this?
