Celica Forums General Discussion Exterior Anyone know what the normal fuel pressure on a 2000 GT?

Im trying to determine if i have a problem with my fuel line, i recently got my fuel pressure gauge, and i was wondering what the normal fuel pressure is, if anyone could tell me please let me know, also my problem is when the car warms up and its idleing the rpms will drop and youll feel the car shake as if its gonna stall but then the rpms go back to 750 then back down and up and so on, this will happen now everytime i idle like at a stop light and all, and im really not sure whats going on. If anyone has any ideas please let me know. Thanks

I do not know, but...
