hmm, on my recently purchsed used evo i noticed something. NOrmally i close hoods by pushin down on it after it clicks...but this particular time it was about..maybee 1 ft to 1.5 ft i let the hood go, and hte motor kinda sounded like it wanted to quit, or on the verge of, than it kicks in again like normal...

 

Mine was hitting the clamp on the UICP and causing a stutter when closing the hood. I just moved the bolt part of the clamp to the side of the pipe and problem solved. Could be the same thing.

 

I have a 2006 IX and it does that same damn thing. It does it every time I let the hood drop from a slight distance up. Just figured I wouldn't do that from now on, as I can't really see anything that the hood would be hitting. But now that you mention it I'll have to double check the hose clamp on the UICP.

Anyone else have an insight into why this happens?

 

It's probably causing the MAFS to get weird readings causing it to stumble, it happens all the time.

 

that's to be expected... don't slam your hood obviously

 

alright , thx

 

 

hahahaha funny, same thing happens to me, like a ft ill let the hood close and the engine looses rpms and a second it comes back up again. i dont know why either, can someone shine light on this?

 

Maf sensor, most likely. Knock sensor, not possible.

 

my friend has jun 272's in his car, when i step right next time when he's idleing his car will start to stutter and sometimes stall or throw codes lol

 

next time flick your airbox with your finger. fun fun fun...

 

really lol

 

haha dude, I thought I was the only one with that side affect

 

its the maf, it very sensitive. my car stumbles and idles bad when a harley or my friends sti with straights is around...

 

Same issue here. I have always wondered what caused that.
