well now it changed it will start all the time but now when its warm it you have give it gas right after it starts or it wil die and it misses for about 40 sec the runs smooth without missing at all, doesnt really make sense but im gonna check the sensor and see what i can find

sounds like your afm has bitten the dust
code 31 is a sure sign of that or you have bad wiring from the afm to the ecu

i think its the injectors im going to do a fuel pressure test and go from there. If it is the injectors, on a NA whats the bigest cc injector I can go with out flooding out the motor or changing out or adjusting the ecu

was looking around on the internet an I saw that you could adjust the AFM, and that the OHM resistance of the new injector needs to be the same. so how big could I go if I adjusted the AFM and cept the ohm resistance the same
