After I installed the VAFC-II. Sometimes the check engine light turn on, but after I restart the car, its off again. However, the light is on no matter how many times I restart it.
When I check the code in Honda dealer, they said the code is about the Vtec.
Anyone know what's wrong???

 

bump

 

what about vtec?? what code are you getting? get a paperclip and check it, you dont need to waste your time with the dealer.

 

is it because the engagement point setting is all f'ed up???....j00 need to pull the exact code yo

 

code 21
should be about vtec. when check engine light is on, the fuel cut at 6000rpm, and no vtec enage.
Thanks.

 

its your vtec solenoid... fix it or get a new one.

 

What do u mean by " vtec solenoid" ?

how to fix it?

 

I think the check light comes on because the Vafc tircks your ECU and it thinks there is an error.

Try disconnecting the Vafc and if the check engin light comes on again it means you have to change you Vtec solenoid.

 

thats true too, the vafc could just be causing a glitch. but if it is your solenoid, check it out.

heres what it looks like

 

Or it can also be that you diden't connect the Vafc correctly!

 

Yo how much are you selling

 

I drove my car today,t eh CEL off. However, when I was driving back to home, I stopped in front of the stop sign. It comes on again.......

HELP ~~~~~~~~~~~

 

BTW, if I connect the vafc wrong. The CEL won't off sometimes, right?

 

Please help
