will some one help me please. i have a hatch with a jdm 16 and nothing done to it but a vafc 1. it is throwing a codes 3 that means map censor. right? ok i got that; now will a vafc make it throw that code?

and today i was camming home from work and i could not get it to go past 3 grand because it starting missfiring so bad that when it did get that hi it would back fire..
i know this is my first post but will some one help me...

 

The vafc1 won't make your car throw a code but it could make it bog out like that if it isn't setup right. Also check your vacuum lines on your map sensor and make sure its plugged in and the lines are in the right place. My dohc zc did that 2 me and my map sensor plug had fallen out

 

ok i replaced the map today and still throwing a code 3 i dont know what is going on

 

VAFC is wired inline with the map sensor to fool the ecu into adding/subtracting fuel. If the "IN" and "OUT" map sensor wires going into the VAFC are backwards, or have poor connections then you would get a code 3. Also if you have the VAFC tuned too far to one extreme, ie way way too rich or lean, it may also trigger a the map code as the ecu is trying to understand what is going on. This case would be a "false" code as everything is functioning/wired correctly.

 

ok thanks how do you set the vafc to the stock settings?

 

In the menu there is an option to reset to default, although I can't remember how to do it. Check the manual and it'll tell you how to reset it.

 

ok i reset it now and going to see what happens now thank you i think i am still throwing a code 3

 

reset the ECU
pull the hazard fuse under the hood and wait for a min then put it back in and see what happens

 

i did jeff now what do i need to do?

 

if you set the vafc back to stock, then reset the ecu. is it still throwing a code? did you reset the ecu? are you sure? pull the hazardx fuse under the hood out for a min, then put it back in and see if your still throwin codes or dont have a clue what im talking about, just give me a call i'll meet you up and do it bro.

 

yeh i pulled the fuse and put it to stock still throwing code
