3k-4k hesitation 01 nbb
As the title states I am having a interesting hesitation or stumble when cold. I will accelerate when it gets around the 3k range it just boggs down then when it is a round 4k it takes off like a raped ape. I am still na at this time. I have changed the plugs, wires and cleaned out the throttle body. Neither of these have done any good. I am shure it has not hurt but there has not been any change.
I am thinking it may be a sticking EGR valve that is causing this issue. Has anyone had this problem? If so was it the EGR or was it something else.
Thank you in advance for any help that yall can give me.
Have a great day,
Jared

VTCS, not VVT. it switches over at 60C.
if you look under the throttle body, there's a green one-way valve on a vacuum line to an actuator. pull that and plug it and it'll leave those VTCS butterflies open all the time.

Jeff- My car is the same cold and hot below the 3kish mark.
Y8s- If I remove the line and cap it will it set a code?
I got a recless driving ticket the other day partially due to this. I think the other part is my lightened flywheel. I think the combination of both makes it exagerated. I was turning left from a stop and it surged and the back tires slid.

Y8s- The car is still stock ECU. I need to get the proper wireharness for my Adaptronic, but first I need to either sell the harnes that came with the unit that I got from Stein or the whole unit.
Have a great day,

Y8s- It looks like that cured the problem. Thank you.
I wonder if the lack of power on warmup has any thing to do with the recall thatwas performed. If I remember right people were complaining about there beeing a lack of power after it was performed.
Have a great day,

I am sort of ocd about the car opperating as designed but I want more power. I know this is very contradictory but that is how I am. Thank you to all who have helped me out in the matter.
Have a great day,

Someone mentioned it might have been part of the factory ECU recall... leave the butterflies closed even when warm. that's silly though.
anyway, it feels like you go from 5-100% throttle because they basically ARE throttles.

You could go the extra mile and remove the butterflies & shaft altogether and profit. Not sure how much power it would be worth but if Braineack went to that much trouble to thin down his throttle shaft (which then lost a screw with amusing consequences) then it must be worth totally removing a restriction in the runners like an inoperative VTCS system.
