Hey guys, i ran into a strange little problem, i notice this after having a clutch installed on my car. My car seems to stall out sometimes when coasting to a stop, usually in neutral. This only happens when it's raining out, other then that i have never seen this problem. The car will stall out and steering wheel will lock up and all i do is just start it up again, im guessing something is getting wet and causing the car to die out. Not sure what it is but anyone have any similiar problem or think you know what it is please chime in. Thanks.

 

yea, my Evo 8 is starting to stall on a daily basis now, not particularly in the rain. I first thought it was my plugs, so I will install my new ones to see if it makes a difference. I also hear a weird buzzing when my car is idling, and when I press my window switch or turn on my headlights, my interior lights dim and the buzzing changes tune, so I think that could be my alternator. What doesn't make sense though, is that the car runs perfect when I am driving, it only stalls when I roll to a stop and am turning my wheel, and then my wheel locks up and I have to slam on the brakes. There isn't any warning before it stalls either, like you can't hear a change in the rpms or feel the car jump or vibrate at all. And my idle doesn't stay smooth when stopped, it will go up and down usually ranging between 400rpms and 1000rpms. If any one has any suggestions as to why our cars are stalling it would be a great help!
Thanks!

Do either of your cars have a lightened flywheel?

 

i would check the maf 1st to see if its dirty or wet, follow by the usual boost tube inspections. i would also disconnect the neg battery terminal while the car's idling to see if its running on the alternator or the battery, if it dies then the alt is no good.

 

I bought my car used, unfortunately, and so I do not know exactly what has been upgraded in my car, only what is visible. I don't know if I have a different clutch b/c it feels pretty stock just as I do not know if there are cams already inside. I DO know it has been dyno tuned by Turbo Trix before I bought it. I bought 272/272 HKS cams, but have not installed them yet, so I will know if I had cams once I take them out.lol. As for the clutch and/or flywheel, I don't really want to take the trans apart just to look at it, I'd rather buy something crazy and put it in while it's apart. So if there are any other possible causes, I'd like to check it out before I take the tranz apart. Thanks for the info!

the greddy type-s you have is questionable. try switching it with a stock valve, reset the ecu and see

 

yea, I am switching to the HKS SSQV BOV and recirculating, however everone I try to order this from is out of stock and there is a wait for it. I alos want to change my UI pipe to a straight one (i.e.-RalliArt) and get a smaller battery. If I do that, then I would need to set up my recirc kit differently. I only wnat to do it once, ya know...anyway. I do hear the Greddy Type-S making a fluffy noise when I'm not under a lot of boost, almost like it's not working properly. I heard somewhere that the GReddy Type-S isn't efficient up to 21+ lbs, which is what I am running.
Thanks for the input!!!

Are your blow off valves vented out or back in the intake? My evo stalled alot when i first got the lightn flywheel, i had to learn how to stop diffrently. Try instead of pushing in the clutch same time as the brakes coming to a stop, try pushing the brakes and let the motor wine down to 1,000 rpms then pushing in the clutch last. One youll save gas because when your foot is not on the gas and its not idling the injectors are closed and your not burning fuel. Two its better for the tranny to downshift coming to a stop, so heel and toeing can help. Other than that check your alt and if that doesnt work take it in. best of luck. Pm if you need any parts or good deals!

 

hmmm, interesting info about the lightened flywheel.......i've never had one, but heard it causes the rpm to drop faster.

the hks bov is not the more popular unit for evos, it's more misses than hits if ya know what i mean. i'm using a aftermarket dual vent valve and had problems even when its fully recirculating(but much better dual venting), i bought a evo9 valve now and will be the only one i'll use.

 

my BOV is recirculating. and I have had this car for about 8 months now and never had a problem before. just recently it has been stalling when braking and turning at the same time. The car will die in the middle of the turn.

That sounds more like the altinator. When you turn the wheel while braking there is more load on the power steering system and that may cause the power steering pump to slow down or speed up and if the alt is going bad it will be affected being directly connected to the power steering pump. I would take it in to a autozone or checker and have them run a alt test to see.
Good Luck!

not to go off the original topic but in regards to #7 isnt the ssqv vta only?

 

They make a version mostly just for the evo that does or can vent back. (fluters alot)

 

i have the exedy twin plate so it came with a lightened flywheel i believed.. but yeah only stalls in the rain, im running a jdm mr bov.

 

you shouldn't disconnect battery cables when a car is running. This can cause a voltage spike which can blow out diodes in the alternator- then you'll need an alternator for sure. Do it right and buy a multimeter for $20 and check the voltage when running- it should be 13.5-14V.

First thing I would do if it is cutting out/dying is clean the battery terminals.
