Message	I have a 92 300zxtt. my fuel pressure regulator had a small fuel leak. i replaced it. car seemed to run ok. then started to go in to saftey boost. wont boost at all past 3-4 psi. i just purchased a new coolant temp sensor and connector and installed it and still same issues. ECU codes seem to be fine. some history. i have jwt ecu and have replaced the injectors with 555cc. i have checked all connectors. car has always had a small stumble problem. what i mean is that while driving you can feel little skips. not all the time. so i thought it was the coolant sensor but replacing that didnt help at all. i dont know what else it could be. could a bad pressure regulator cause safety boost? car runs ok just wont boost. any help???
