I was wondering if I could get some insight on a code I’m throwing. I’m throwing P0092 I know what the code is Fuel Pres. Reg Ctrl Circ Hi; I just don’t know what would be causing it. It started happening when I was getting on the freeway and I was on it, it would happen in high RPM and shifting in the 5th. Now it has become progressively worse. Now it’s happening on just the road and when I’m easy on it and shifting in 4th or 5th. I don’t know if it’s a bad fuel reg., or weak cp3 or injectors? Hope someone can help.

Thanks

Changed my fuel filter and still throw the coded. I'm hopefully going to put my lift pump on this weekend but does anyone have any advice.
