I'm having this problem in my 05 with a type s (spring mod), test pipe and catback. When I ran this setup with my 03 I didn't have this issue. I'm not sure if my 05 did this when it was stock. I only drove it for less than 100 miles before I put some mods on.

 

its not ECU either I dont think, mine started right after I did the XEDE and making more power and blew off a vacuum hose, so I tried using the stock BOV.....still did it....so i unhooked the XEDE and used just stock ECU....still did it...So I have ruled out that its not the XEDE, and its not BOV related. Clutch, i dunno, im still on stock. I wish someone would find a fix though.


Oh and it also seems to be weather related...It only does it the most or at all on cold days.

 

mine does it regardless of weather temp.
ok, does everyone who has this problem have a test pipe?

 

i experienced the same problem....i ve also been drivin manual cars for years....and its not becuase i am not takin my foot off the clutch, becuase the minute i do the throttlebody closes, BOV opens, then RPMS raise...still cant seem to figure out what it is...but workin on it

 

i had the same problem in my previous WRX....
i think it caused by 1. ecu. 2. mbc. either one of those is not setting right or not corresponding to each other.

 

thats an Idea...I do have a MBC, but have had it on for a while now... I could and should be using the XEDE to control boost, but have yet to get it hooked back up. I can put it all back together to be able to use, but my problem would be setting up my XEDE to use boost.

 

guys, that may be the problem. MBC
mine is a buschar MBC and it was leaking boost so i tighted the two bolts that hold the nipples with two wrenches. it may have been the problem.

 

I dunno how it could be related to a boost leak?? I honestly doubt it has anything to do with boost control either, guys who are stock are saying they have the problem.

 

is this problem not common? is it just a few people that have this issue?

 

im beginning to think its just a select few.

 

My car does this too. It isn't me not letting off the gas because it did it when I took my foot off the gas to slow down for a stop sign then put clutch in to stop completely. I hadn't hit the gas in atleast 2-3 seconds before I put in the clutch. My car is completely stock with only 550 miles on it too. I would really like to know what causes this......

 

yeah, it wont do it at all without pressing in the clutch.

 

Try Japeneese foot binding. Your big foot is probably dragging on the brake pedal and you are not getting completly off the gas like you think you are. Seriously though there are certain shoes that I have that will not allow me to shift this car efficiently.

 

ok thanks for the advice.

 

The pedals are definately pretty close down there, but I have had my Evo now for about 14 months and this only started happening about 2 months ago. I have 23k on my car and about 6-7k on my ACT clutch. What about the clutch adjustment under the pedal?

The mods I have done since this started happening are HKS cams, UR Test Pipe and TT flash.
