today afterschool after I dropped off 2 friends and was on my way home, I approached a yellow light while i was on a roll, so i decided to gun it to get by on yellow instead of braking hella hard. when i gunned it I got a check engine light, i pull the code and get CEL45 which has happened before and I just reset it thinking that it was the fact that I went too throttlehappy without warmup.

Can anyone tell me what could possibly be the culprit to this problem and what to replace or fix?

the CEL says its something wrong with the fuel monitoring system.

this is on a 98base btw.
