I have been to hell and back for this car. as of now the count stands at 1 engine, 2 transmissions... point is.. in total it's close to 15K or more. I have a bank 1 too lean code. I have new o2's, a new cat, new exhaust, new engine(2 yrs), brand new tranny, I have a CTA intake. why the F am I getting this code after all this work. I've been through at least a dozen mechanics/shops. I am fed up. I hope someone here can offer some advice. Tomorrow I take off the CTA and swap for the stock intake system, if I throw the same code, I am at a loss for ideas. Someone please help before this car gets a one-way ticket to the bottom of the atlantic. thanks.
