I have had the VAFC installed for almost two years now. I am experiencing rough idle. Is it possible the VAFC needs to be re-tuned? Only other thing I could think of would be valve adjustment.

I am taking it to the dealer so I just want to know ahead of time if I should disconnect the VAFC or if I can elave it on because it doesn't affect the idle.

 

maybe a vacuum leak or pcv or iac? i doubt its the vafc needing to be retuned.

 

the only way it would cause bad idle is if it wasnt tuned correctly or it lost its tune.

Check other things. Vac leaks are a good idea

 

If I had a vac. leak; would that also affect braking? i.e. Pedal feel; it maybe not feel as stiff?

Yes.

 

Hmm, well that is what I have. So then that sounds like the issue. Hopefully Acura can figure it out.

What should the vac. be? Is this in the Helms somewhere? I can have Acura test it.

i vaguely remember reading about vac pressures and problems in here before. might wanna search around a bit or check the helms.

 

Hmm, I did a search and found nothing. Any ideas on topic title or keywords?
