Okay, i have read the threads and can not really find what my problem could be, I first was thinking it could be my fuel pump. I do have a inline fuel booster on the car so i was thinking that should give me the fuel up to the Reg. Here is the problem
With the car at idle with the vac line off, i set it to 43.5 Psi, If i go to Wot With the vac off the fuel pressure will stay at 43.5. When i put the vac line back on the pressure drops to about 38 psi, Now with the vac line hook up when i go to wot the fuel pressure goes up to 43 for one sec. then drops down to about 30psi. Is there since the cam is pulling to much vac? I am clueless here, i did change out my fuel filter and checked for leaks none where found, i pull my 32lbs injectors up and none are leaking as well. One other problem that i have is that the fuel pressure does drop to 0 after the the pump starts up when you turn the key, I also check for vac leaks and could not find any. The Histogram is reading lean, S trim is about 140-150 if i boost up the fuel pressure to about 54psi with the vac hook up i will get about 128 in the s trime. But the long trims are staying at 160's, i pull an 02 sensor and that thing was whiting then white. Also about 2500 i was getting a spark adv. of about 41.. Any ideas?
