yeah it starts up and goes to about 2k then it up and dies, it throws a code 10(iat) but it hasnt always done this and it always threw the 10

 

crx si, stock intake manifold, stock ecu- i think pr9 or something obd0 for sure all i did was wire it the right way according to the manual because the dumbass i bought my car from had it messed up the oxygen sensor wasnt even plugged in anyways

before- no oxygen sensor in exhaust wires messed up-------car runs but revs slow because too rich

after- oxygen sensor hooked up wires in place according to manual---------car starts and revs faster, but all of a sudden dies

before it threw a 6, 10, 13
now it only throws a 10
you would think my car would run better now, but i beg to differ.......................
please help me this is my first car, and if i cant get it running right im going to need another one
