You either hooked it up incorrectly or set it incorrectly.

Read the instructions. make sure it's set on 4 cylinder mode and has a sensor # of 6

 

will it do that if im missing an o2 sensor

 

It won't run very well if your primary O2 is missing. The secondary O2 will not cause any issues other than a CEL.

 

alright thanks guys and its the 02 sensor towards the back of the car

That isn't causing your problem.

 

Did you do the initial setup, it says wit a caution beside it, turn key over (dont turn car on) and go through the initial setup. And make sure you have tps (dont kow if it has a map voltage) set correctly voltage wise, there is a choice of declining and rising voltage. (which is when you press the gas, voltage goes up or down, that may be your problem)

 

i noticed that the voltage goes down when i hit the gas

 

also i dont know too much about it i bought it with no directions or anything just the vafc so i dont know how to do the setup stuff

 

go to the apexi website. http://www.apexiusa.com, I think. You can download the instructions for free.

 

, hope you have high speed
