hey guys, i have a 77 280z and i recently replaced my fuel pressure regulator with a cheap adjustable aftermarket one to see if would fix a other problem "stupid move". this regulator said adjustable but it really wasnt so it was running around 50+ psi.. i never really ran it on that kind of psi but the otherday i had to move it out of my driveway for a second and it seemed to be running normal then all the suddin it started running insanly terible. it seemed to idle ok but when you touched the throttle it would instantly sputter. whell after a while of trying to solve this problem i fell unsuccessful and put it back in the garage. a few days later i try to start it and it will barly start and sounds like its only running on 3-ish cylinders and does not idle. still cant figure it out, a day later i go and try agian and then it fires maybe once for one or two cylinders and dies. im not sure what this problem could be. my best guess is that because of the high psi it has broken or jammed some or all of the injectors. today i replaced the regulator with the stock one and banged on all the injectors to see if they would come un-stuck. i did have some breif success, it started and ran on 3-ish cylinders agian. if you guys have any idea of what this could be please let me know, thank you . sorry for the long ass story.
