Hello everyone,

Not having much luck with my 300zx tt at the moment electrical faults galore but managing to bottom these problems. Anyways the problem I have now is that my car idles up and down then sometimes decides to settle at 1500 rpm then at the next set of lights it goes to 600 rpm an some times cuts out and if you give it some it will not go past 5k it just starts to splutter and revs drop all of a sudden.i have taken my iacv off cleaned and fitted back with new gasket changed plugs checked all connectors I can think of ptu etc all ok. Going to ohm test my injectors tomoz as well as run a diagnostic test but anyone can think of anything else would be much appreciated thanks in advance an sorry for the long post haha.

Have you done a boost leak check yet? or and set the throttle balance, TPS position and timing, all basic start points, then get it on a ConZult and check the air flow meter readings and injector readings and look for any codes.

No not sure how to do the boost leak test but will do some searching an see if I have the tools to do it I have a multi metre so can check the injectors. See how far I get tomorrow maybe time to take it to a garage. Thanks for the reply Jeff really appreciate it costing me loads this zed lol...
