I have been working on this car for about a week now. The car will start up and idle fine, but at about half throttle the car boggs down and wants to stall. Sometimes it stalls and other times it picks back up. The fuel filters have been changed and there is fuel at the injector rail and it will spray out, but the pressure will not read. I have no clue where to go because the pump will make noise and sometimes the throttle will respond but sometimes it doesn't.
Please help!
Thanks!
