Engine Performance problem
1991 Jaguar XJS V12 Two Wheel Drive Automatic 16000 miles
I have a 91 jag xjs. Vehicle stalls after running for a few minutes. Acts like its running out of gas. I have replaced the crank sensor and the fuel filter. Still has this problem. I checked the fuel pressure by removing the return line on the drivers side. It went to 80 psi. I looked up the specs and should be between 36 and 46 psi. But the engine boggs down and will die if you continue to throttle. I am a long time tech of GM and Chrysler. (24 years) It really acts like its running out of fuel. What am I doing wrong?
