SpecBGuy Posted February 15, 2013 Share Posted February 15, 2013 i have around 29k on my car with no engine mods beside cobb ap and air filter. when driving in traffic or low speeds of 5-15mph my car gets that pull feel, like when you release the clutch too fast or like im slamming on my brakes. i dont know what its called or how to describe it but any better way. car is fine at normal speeds but just in traffic or areas where i have to drive slow it seems to be having that problem.. any ideas before i take it to dealer thanks Link to comment Share on other sites More sharing options...

It lurched forward then stops like you are stomping the gas then letting off abruptly. Another question have you noticed any throttle surge lately when the clutch is in while in stop-n-go traffic ?? My guess is the rolling idle speed is mapped to a table that relates to the speedometer and when you just want to creep along, in gear no throttle input but picking up speed, it doesn't like it. I particularly hate when this happens b/c something in the bell housing make that metal smacking sound Link to comment Share on other sites More sharing options...

Another question have you noticed any throttle surge lately when the clutch is in while in stop-n-go traffic ?? what do you mean by throttle surge I particularly hate when this happens b/c something in the bell housing make that metal smacking sound yea sound like my whole engine is about to fall apart or something. last time my bro-in-law was with me and he thought i was letting the clutch go too fast but i told him that im not doing anything wrong the car has a mind of its own. so i guess im not the only one with this problem? gee-otto are you running on stock ecu or any other map Link to comment Share on other sites More sharing options...
I Donated Too sigmafour Posted February 15, 2013 I Donated Too Share Posted February 15, 2013 must be something with the 2.5 engine - I am pro tuned and have the same thing at low speeds, not really worse or better hot or cold but I notice it more when it's cold... others I know including those with 2.5 engines in Impreza's are also and have reported the same stumbling feel, it was not so present in the stock tune but it is now and was the moment it got tuned. It doesn't seem to happen to every car but it is common enough. While it could be annoying I just deal with it, there's no harm happening to the engine.

I Donated Too sigmafour Posted February 17, 2013 I Donated Too Share Posted February 17, 2013 there's a few cars that DON'T get this problem under what should be the same conditions - but more than most do... there is no rhyme nor reason for this.

SpecBGuy Posted February 20, 2013 Author Share Posted February 20, 2013 thanks for the links sigmafour. i would have searched before i made this thread but never knew what this problem was called. as long as it doesnt cause damage (which who knows it might be) ill just leave it alone. i dont want to spend money trying new maps, spark plugs, throttle control and etc. thanks guys Link to comment Share on other sites More sharing options...

Another test is once you notice this occurring int traffic, get up to 30-40 MPH, push in clutch, leave car in gear, see if RPMs surge up to 1500-1800 Another cause that a member suggested to me was that the Neutral switch was failing Link to comment Share on other sites More sharing options...
GEE-OTTO Posted February 21, 2013 Share Posted February 21, 2013 i remember the first couple times this happened to me... "oh god, faulty accelerator, gonna die!" My only issue with this problem is my legacy isn't as smooth as it once was I want to be able to work the clutch in traffic and not appear as if i'm on the brake and gas and clutch at the same time all the time.

SpecBGuy Posted February 21, 2013 Author Share Posted February 21, 2013 i remember the first couple times this happened to me... "oh god, faulty accelerator, gonna die!" :lol:first time for me i was like "fck there goes money for koni that i need" and second thought was "please dont die on me right now please :redface:" Back on my stock map, I called Mach V and ask about logging while it is acting up to see if it provides feedback. Another test is once you notice this occurring int traffic, get up to 30-40 MPH, push in clutch, leave car in gear, see if RPMs surge up to 1500-1800 Another cause that a member suggested to me was that the Neutral switch was failing if you do get some feed back let me/us know i dont think i can go 30-40 in traffic unless i stop and not move for 1min or so but ill give it a try Link to comment Share on other sites More sharing options...
