i have a 92 civic hatchback si with the stock z6. it has intake, mild headwork, header, and exhaust. when i get around 6 grand or higher in second gear and shift into third fast the CEL comes on. i checked the codes and it was 43(fuel supply system) and 22(oil pressure switch). when i turn the key off and back on it gos away.

when i bought the car a week ago the kid told me in need a vtec silenoid and i had one laying around that i knew worked so i put it on and didnt make any diffrence.

i was reading about code 43 and put a fuel pressure gauge on to check the fpr becouse it was easyist to check and it was fine.

the car dosnt run bad i just dont know why it would throw code 43 and 22 at the same time and both go away when i shut off the car. should i try taking the neg off the battery sence i changed the whole silenoid and pressure switch and if so whould it have anything to do with the fuel supply system cel at all?
