my idle is horrible with this dv. my car died on me once when i put it on neutral to come to a complete stop. i changed my plugs and i put my boy's 06 mr dv on just to see was there something wrong with mine and it's still the same. rpm sometimes drops to 300 and then goes back to normal. when i put the plastic dv back on my car runs better. why is that?

 

are you putting it on backwards?

 

it sounds like its in backwards. Same thing happened to a buddy of mine

 

nope i dont think so..the nipple suppose to be facing up right? the top of the dv suppose to face sideways and not up right? im sure i installed it right.

 

Bottom port goes to the UICP side port to the intake

 

is it broken?

 

Hmm... well if you say its not backwards, then it shouldn't be.

Check all your vac lines.

Make sure everything is tight.

Can you push the DV open with your finger super easy? its weird that you tried two IX valves, and they both gave you the same result. makes me thing the problem is else where?

Try throwing your stock DV back on, and see if the problem is still there.

 

my car runs better with the plastic dv..idles smoother and boost feels better.

 

hmm. thats weird. Well.. since you tried Two different IX DV's...<Br>

i suppose you're only other option would be to switch over to a Forge or somthing?

 

this sounds strange since my jdm mr valve improved my boost response and idle is just perfect as before

 

Just my 2 cents, but my Evo almost...ALMOST...stalls every time I go from rev into gear.

 

are you venting it out in the atmosphere?if so it will stall on you

 

Maybe the JDM MR bov is leaking on you or defective. Have you tried to do a leak test?

 

He tried 2 separate ones, so it's not defective. There is a definite problem, but it makes no sense that the JDM MR/EVO IX DVs would cause these problems.
