I have a 1989 Z32TT runs fine when first started then after a couple of minutes the idle becomes erratic and engine starts to miss, once it has reached normal running temp it seems to be fine. is fitted with series 2 PTU new plugs & fuel filter have just cleaned throttle bodies and have checked all the wiring connectors, ecu does not show any errors, was thinking maybe faulty CAS unit anyone got any ideas
lots of possibilities Here's a couple to start with, Coil pack and injector plugs, check again and maybe retension. TPS setting, make sure it is in spec, check tech section for how to do this and for the proper voltage setting. Other people will more than likely add to this list so just keep going till you get it sorted. Hope this helps, Andy
