Hi there,
I own a 2005 Honda Jazz 1.4 SE Sport.
I have been receiving a jerking effect with my car which happens sometimes when at higher and at lower speeds. I had the EGR valve cleaned and spark plugs changed which made no difference.
What I noticed is that when I put my foot all the way down on the accelerator, when my car reaches 45mph-50mph, it doesn't push any further (makes a hissing type noise) until I release my foot off the accelerator and slowly increase to that speed at a lower RPM. At that high speed, when I release my foot off the accelerator I can hearing a whistling type noise.
I got the car scanned and the error code 22 came up about the vehicle speed sensor. I am not sure whether the problem just lies in this which causes the jerking and me to not accelerate at high RPM, with wiring of this sensor or there is a problem with my gearbox.
