Hi every one heres a little poser for you lot

when my z is stationary and i hold revs up to 18/2000 revs the car either vibrates or is missing very hard to distinquish which any thoughts! [91 uk tt auto]

cheers

PS just removed my stock radio/cassette and cd player [under cassette]out to fit kenwood demask system do i keep the frame work!! in which the radio cassette/ cd player is carried to enable me to fit said system or leave it out?

Manual or auto? I think they all have a little resonance about those revs, not a misfire. Does it drive well otherwise?

Hi willieO

the car is an auto and drives fine a bit notchy but ok

cheers

Try a cilinder balance test. Then you can see if one of the cilinders isn't working properly (no RPM-drop). If this is the case at least you know were to look further.
