    I was just thinking about this post.

    For me... I replaced my Stock BOV with my APS and that bucking seems to have gone away. I mean I still have motor mount movement. But the over all hesitation feeling seems to have smoothed out.

    I let the dealer check it out and they said it was normal. They didn't say what causes it. I don't know if it is my imagination but since gutting the uppipe the problem seems to have become less noticable. It is still there though.

    I understood that a grounding mod would fix this problem. It would help smooth out the readings from the 02 sensors and create a smoother on/off-throttle ride. I don't know if it will fix it, because I haven't gotten around to doing a grounding mod yet. Anyone have a grounding mod and NOT notice this problem?

    I say this because,
    One of my friends has a JDM B18 put into his EG6. The engine runs fine, but it had a very strange jerkyness to it when he'd let of the throttle and got on it again at mid RPM. He did a custom grounding mod and the jerkyness disappeared. I figured it was under the same principle.

    grounding mod didn't do crap for me except blow money. However it will benefit me when I put my stereo in.

    The bouncyness went away with my BOV swap.

    I just got my prodrive stage 2 chip and that fixed everything, it made the car so much smoother. I don't know what they did, but the engine is very smooth now. not to mention more power

    It must be something with the ecu then. Some setting that creates the bucking when giving slight throttle. I hope to get a utec soon, so I hope that will help.

    I get a weird jerking feeling when I'm anywhere from 60% to WOT. As soon as the turbo kicks in, I get this weird jerk, like it kicks in and out, that's usually around 4000 RPM... its kind of annoying.

    I was doing some research on short ram intakes and found a guy that said his car was running like it had air bubbles in the gas lines after his short ram install. Kind of like what we are experincing. The car is kind of jerky, like it gets fuel cut for for a fraction of a second. I wonder if it has something to do with the stock air intake? maybe we are running lean or something?

    Another thing i noticed is it is different on different days. Some days it is more noticable than others. I hope to have a UTEC soon so maybe that will solve the probs.

    I feel the same way. Some days its smooth as hell, other days I feel like I'm driving a tow truck on steroids.

    I was just going to say the same thing, both my friend and I had this problem but his was much worse, my friend made a grounding kit for us and our problems are gone. I'd say the grounds suck in the WRX.

    Another thing I noticed, it isn't really noticable when the car is cold, I notice it more after about 1/2 hour of driving. The adjusments the ecu makes after the car warms up seems to cause it. I might look in to the grounding mod. I am definatly going to get a UTEC someday.
