hi guys, my z32 has had an idle problem since Ive gotten it, it has good power past 1500 rpm, no bogging, but at idle shakes the car and from idle to 1500 rpm seems to bog a little bit, did a compression check and that's good, have new spark plugs, all coil packs ohmed out good, don't think i have any vacuum leaks, don't have any check engine light, only thing Ive found is one injector ohmed to 28 but still makes a twaking sound when i listen to it , obviously this injector needs to be replaced, but is this my idle problem or should i keep looking for the culprit, has anyone had this happen to them

thanks

 

so i checked alot of stuff out and turns out it was my power transistor sub harness had alot of green corrosion in the connectors. tried to clean connectors up a bit and it ran better but car still shaked at idle. just put in a new ptu and sub harness and it seems to have taken care of that problem. on z1 motorsports, it actually says these are known to go bad and when they do the car will shake at idle
