we just put a 99 b18b in my friends 96 dx hatch. we got it running and warmed it up on the stock dx ecu. it idled fine but when you gave it gas it surged. we figured it could have been the ecu so we put the teg one in and it did the same thing plus it wouldnt idle on its own. right now its on open header because its a little late to go to an exhaust shop. anyway if anyone can help with this it would be great. i tried searching but didnt find much. thanks in advance.

 

Is it throwing any CEL's?

 

we figured it out we had to repin for the iacv on the ls ecu. not the only thing is that when you give it gas and let off it backfires a little. i have my friend bringing over a timing light now. what should degree should it be set at?

 

if you're running obd2, you need both primary and secondary 02 to function WITH a catalytic converter on...my b20 was bogging until i put a cat on, it stopped.
