Hello all, I'm posting here hoping to find some Celica and Toyota specific knowledge. The vehicle in question is actually my girlfriend's, a 2002 Celica GT. She has her inspection coming up and the car is throwing some trouble codes. P0171, P0440, P0441, and P0446 are all the codes I'm getting. I've cleared and re scanned the car at least 3 times and the codes are consistent. I really don't have a large knowledge or familiarity on these cars because I've never owned one. All i know is that it's a 1.8l, it has 258,xxx miles, smokes a bit and leaks a bit of oil, but otherwise is a good running car. It came with an aftermarket intake and a straight pipe after the cat. Now I know off hand there's some sort of evap or vacuum line disconnected by the intake, and when I noticed and tried to hook it up it made the car want to barley run, so I left it as is. I'll try to get some pictures. Just wondering if off those sets of codes anyone would be able to point me in the right direction. Looking into the codes only gave vague results all essentially saying the same thing in different ways. Any help would be greatly appreciated
