fuel pressure a/f question
What i am wondering is if your fuel pressure is weak will your a/f lean out? I am having problems making power after 5200 rpm but my a/f remains at 12.8, my lower rpms are very responsive. I dont have a pressure gage but i have a wideband. I have no trouble codes and my car idles and drives great under normal driving conditions. could my fuel pressure be weak? thanks
