okay guys well i have searched and found alot of things about the P0171 code, lean bank 1.....where should i start on fixing this problem....i'm thinking about injector cleaner, cleaning the maf and new 02 sensors.....any advice?

2 words. Seafoam treatment. Do it in a place that has alot of open space that stuff makes alot of smoke.

i will do a search, but i'm not familiar with the seafoam treatment...can you do this on a sc'ed car...what exactly do you do?

thanks man.....so to get it in the intake, you just pull off that brake line/booster and pour it in there (8oz) and the rest in the fuel tank?

yeah thats what I did to the supra but remember it makes alot of smoke people may think your car is on fire.

well i seafoamed lastnight and it smoked like a banshee....i put about 8oz in the brake booster line and the rest in my fuel tank..i also cleaned my maf sensor with electric cleaner...i probably need more than just 8oz in 15+ gallons of fuel......well anyway i got a check engine light lastnight and then after driving 25 miles this morning i got the p0171 cel again! so maybe it will just take some time to clear things up...is it possible that i need to change my O2 sensors? i raced my brother the other night and when i hit 4th gear, i lost all boost and he caught me....this is driving me crazy..... any help appreciated!~

if you have an injen take it off and put your stock airbox on

by **shocar4** » Thu Sep 14, 2006 1:25 pm

i have the stock air box with k&n drop in filter!

If you're boosted and running lean, I wouldn't jump on the gas too much.

that is what burns holes in pistons

by **shocar4** » Thu Sep 14, 2006 2:03 pm

i think that it is a false signal caused by an air leak or sensor rather than actually running lean, because i have all the proper upgrades to supply sufficient fuel to the car!

CEL= Center Entertainment Lighting System. Party on bro

by **shocar4** » Fri Sep 15, 2006 6:04 am

so does anyone think that i should change my 02 sensors?

by **Astro** » Fri Sep 15, 2006 7:34 am

Remember, you have air/fuel sensors in the front and rear banks and an O2 sensor near the cat. I don't think you need to change the air/fuel sensors though.
