Thanks Tom. I think tonight I will get the car out of the garage, set the Monitor 2000 on record mode and see what kind of O2 numbers I get at full throttle. If they are both lean, than it's time to change the fuel filter and check out the strainer. I can't imagine how the fuel pressure regulator could cause the pressure to drop consistantly.

Actually, I did drive the car around the block last night and while it did cut out, it didn't seem as bad as it was before.

Anybody know what the O2 sensor readings should be at full throttle? I'm thinking in the .800's but not sure.
