Wus up fellow evo members! i have a problem that i dont think no one haves the answer to, i have a evo 8 gsr and i upgraded to the mr bov when i changed the bov my evo will almost stall in stop and go traffic or moving in real low rpm's like i drive up to 1500rpms then put back in neutral and it dips down to 200 rpms? then rise up to normal idle the car idles fine its just when im in low revs she wants to stall and its defenitly the bov because i put the leaky plastic one back and problem gone and i read alll the threads that point out this problem but No one found a fix or the cause i have no vac leaks or boost leaks did any one fix this that can help me out thanks.

 

Is the MR BOV crushed?

N

 

its not crushed i purchased one used and bought a new one as well its not vta ether any ideas?

 

do both the used and new one do it as well?

 

Did you install it backwards?

 

both did the same thing and was installed correctly, there 's forums on here with alot of people with the same problem i try to contact them to see if they fix the issue but no response any one running a mr bov without issuses?

 

Mine run's fine without any of those issues... You have the vacuum line hooked up?

 

ya the vac is hooked up and my boost gauge reads 20psi at idle, you have a mr bov on a 03 evo?

 

i have an mr bov on my evo 9 and have had no poblems with it

 

are you running a after market intake?

 

That's odd, is the car on some funky tune? And did you mean -20 at idle? If your boost gauge reads 20psi at idle your gauge is hooked up wrong or you need a new one.

 

ya i ment -20 at idle and i had it tuned by ivey

 

Mhm... Have you checked the bov hose for any tears? Sounds like there could be a small leak somewhere

 

i replaced the hose to the bov but if it is a leak shouldn't my vac read lower than -20 at idle or idle funny?

 

Yep.

This.
