P0172, p0175

97 stock Z28, driving home today my car started idling REAL rough. CEL came on shortly after, when i got home i ran the codes and P0172 and P0175 both banks running rich. the car will not start unless the pedal is floored and even then it takes a few seconds longer to start plus you can smell raw gas. fpr not leaking fuel, LT fuel trims are staying at 0 and the ST trims are going as high as -37 on both banks, also the temp sensor is reading fine. evap, egr, and rear o2 have all been removed and tuned out for a few years now. anyone have any clues as to where to look next?
