I was wondering if anyone else has noticed a little hesitation at 3000 rpm when driving. When driving an hitting 3000 revs the car will hesitate then speed up.Is 3000 link to vtec. I am driving normal speed not to hard on gas. Also when AC is on it is more pronounced. 2013 Sport Manual.

 

the vtec threshold is around 5400 rpm.

Can you describe more what you feel? Is this with constant pedal pressure? What gear are you in and what speed? Were you accelerating before you noticed this?

 

I have felt the same thing. I only feel it when doing partial throttle acceleration. To me it almost feels like a little misfire. I was also wondering if it was VTEC kicking in.

 

Steve244 just like mr.ramsey said partial throttle. Increase speed . It does it in any gear. Not looking at speed though. On the highway it does it when just adjusting RPM at around 3000. Feels like a automatic tranny. It's noticeable because when it happens I know I hit 3000 because car feels as if a rubber band was holding rear bumper then snaps and you go. Car has 7300 miles and has been doing it since new. I figure either fuel mapping issue or throttle by wire issue. No biggy just wanted to see if other people were having the issue.

 

4500 on mine. Sounds like the same thing I feel.

 

Well just went for a spin. It did it at around 2600 in second gear with very moderate throttle. It I use a more persistent pressure on throttle it does not do it. It has to be very moderate then when car hits around 2600 it just takes off. Like someone just thru 10000lbs off the back of car. Does it in 5th as well on highway when hovering around 3000 revs and applying light pressure. Thinking maybe TBW jitters.

Don't notice it in an auto.

I suspect it's the normal power-band. You're hitting the sweet spot and notice a difference; it's designed to produce power at RPM.

Otherwise I could say it's detected knock and retarded timing and this corrects when a higher RPM is reached and the knock ceases. I could also suggest using premium fuel and see if it's any different, but this would be against my morals.

 

Steve244, I will try the prem fuel and see if there is a difference.

 

ohhhh the shame...

 

I have only used premium fuel since new. Of course after Colnago posts this thread my car seemed to stop doing this. Or at least I can't re-create it now.
