I keep on throwing a lean on bank one code not sure what the code is off the top of my head i was wondering what it could be from and how i can solve it. I just got back from iraq so my car sat for 13 months, but i have been through a few tanks of gas since if been back so i dont think it is the gas. I also installed new ngk plugs one step colder gapped at .45 in prep for my stage two. (stage two not installed yet). Also a megen catback exhaust, and a injen cold air intake if you guys have any suggestions im open to them. thanks I also forgot to mention that the code did not turn on right away it took about a day and a half to come on once i cleared it took about a day for it to come back on.

 

From the intake. Almost always in my car.

Threads merged, no reason for 2 of the exact same threads

 

Sorry i tried to delete it i needed to add something and it wouldnt let me.

 

i think its a O2 sensor

 

disable it..or get a tune

 

Why are you running stage 2 plugs if you don't have it installed? Go back to stock plugs.

Also, try .040 when you do get it installed.

 

colder plugs are not a bad thing on our stock set up. wont hurt a damn thing and should dissapate heat better than stock platinums.

but i agree, gap should be between .035 and .040

you most likely have p0171 lean fuel trim code. common thing from aftermarket intakes. a lil maf tuning will fix this minor problem.
