Hi. I have recently bought an 03 zr. It holds back at 3000 revs if given a lot of throttle but if given throttle slowly then will pick up speed. Timing has been checked, new coil pack, new camshaft sensor, new fuel filter and injectors checked. Where would I proceed from here please? Thanks...Alan

Any codes set? sounds like a faulty TPI sensor, check codes first and report back the findings.

TPI, Throttle position Indicator, its part of the throttle body, it indicates the actual throttle position opening, run a scan and see if you get any codes.
