OK, It's built. OMFG that cost a lot (ouch) now I have a question. inbetween 3-4k rpm (without O2 sensors or mass flow sensor hooked up) It will start chugging when u hammer on the gas.... like it wants more air or wants to die.... the idle is a little weird too, till it warms up. I am going to have the O2 sensors installed next week (damn aftermarket exhaust header) Will the absense of the sensors cause something like this? should i just short the contacts? or maybe use a resistor?? Anyone with extensive advanced CRVTEC knowledge please respond.
