i have a b16a2 that is already in my 94 dx and is not running right. i know the idle motor sensor is broken, it has all the fluids and a new timing belt on and it goes but not like it should.i have checked all the sensors, fuel injectors, new fuel filter. It wont go fast enough to hit v tech. Help me please!!

is the cel light on?? what ecu are you using?? i'd change that broken sensor first

yes the cell light is on, i am using the scu from japan that came with the ecu and im using the stock wiring harness

i dont know if this is a simailar problem but my friends motor would not engage vtec at all but yeah ill tell him to look at this thread...

start by fixing what you no is broken and get the ECU out of limp mode, so it will work right to start with.
