RE:Intermittent Problem

OK. Over the weekend I used the paper clip routine and jumped the pins on the data port to pull any codes that might be stored. All it flashed was a "12" which I believe means that the system is working and there are no codes stored.

I hooked a FP gauge to the fuel rail. As soon as I hit the key and the pump cycled. The pressure was immediately about 41 lbs. I started the car and at an idle it kept about 36 lbs and goes back up to over 40 when I blip the throttle.

I let the car warm up and took at for a drive with the FP gauge still attached and taped to the windshield. I tried to recreate the conditions of when the car gave me trouble but of course she drove just find. Pressure was a steady 36 lbs and rose back up to over 40 when accelerating.

Any ideas?
