ive searched alot before i posted this i just did a b18a1 swap in my ef and now my car is runnign to lean i read that the o2 sensor can make it run lean so i changed my o2 sensor. i am throwwing codes 5 and 7 the map sensor and the throttle position sensor and i dont know what i what to do to see if those are workign properly can anyone help me out with this? thanks in advance

 

dont worry about the TPS unless you have a idle that annoys you...the map though may cause the car to run rich/lean ...i would just replace it but before you do, check ALL of your wiring from the swap...and if a buddy has a p75 ecu laying around, throw it in and see if you get the same codes

 

did you have a si or a dx before the swap and was it dpfi or mpfi.

 

You may have switched the plugs. Try swapping tps and map plugs. seen it before.
