Topic starter

Hey Ol' Scotty!

Love the channel, asked an employee at autozone (I live in Hamden, CT) about the AT205 reseal he said he never heard of it. I asked if he knew you and sure enough he DID! I told him to go rev up his engine and watch more videos! Anyway I got an 03 Camry SE V6 135K, code is P0171 and P0174 bank 1 and 2 are running too lean. My dad changed the mass air flow sensor, did nothing. Last week he unattached the fuel line going into the engine (under the air filter) but instead of spraying out hard it just dribbled out. I ran a fuel cleaner through didn't do anything. Any thoughts?? I'm still learning but maybe the fuel pressure regulator or the fuel pump? Can't pass emissions till we figure it out. Please help! I watch you religiously and I'm buying some merch (the grey scotty t shirt and the t shirt that says 5COTTY on a TN plate! You're sense of humor is so relatable and you share your knowledge in a way I can understand seeing as how I don't know much at all. I really hope you see this, on days when I need a laugh you're always there 2x a day making me laugh at those animal pictures and elon jabs! Sorry I'm a talker you'll probably have to summarize LOL!! You're a good man Scotty! Keep sharing and laughing, we fans need you! Thanks again Scotty, now nexxtttt quessstionnnnn!! Is it okay to drive with banks 1&2 running lean? Seems to run okay but I do not want to ruin this car, I wanna drive it till at least 500,000 miles!

The message isn't that long.

Other possibilities: Fuel injectors are clogged. The fuel lines are clogged. It could well be the fuel pressure sensor, as you say, or the fuel filter/pump. 

Or, alternatively, check the air intake (cabin air filter, engine air filter, etc). You could have some kind of vacuum leak. I'd check that first, or have a diagnostic mechanic use a smoke machine. See Scotty's video (below):

Geriscan is correct.  For your reference also see here:  P0174 will be similar as well.
