I had same trouble , turned out (after many hours and swear words!!!) to be broken wires at the plug connected to the injectors , could also be bad connections! some of mine were green looking!
looks to me as though its the water pump! but it could be the thermostat housing seal !!! or one of the pipes from thermo housin or clips!! good luck!! :smash:
Ok another prob with my Z!! Appears to b running very rich , above the exhaust the bumper is sooty black !! anyone know any common problems with them, sensor or something?? if give car a fairly good rev u can c the black haze from exhaust!! :( :( :( :( :( :(
Only thing i can suggest is try the rev lights both at the top and both fogs below if that possible !! need to look at my own as car up for mot on fri!!!
Yes fluid level fine , all wiring been checked by my mate who is nissan mechanic , hes looking into the hicas at work ,says there is not much info on the 300 at present !!
Yes have have a momo wheel and boss on ! speedo once stuck at zero !! happened once in 6 months,, any ideas??? dont know about the boss but i think its is the correct one fits nice and snug, how would the boss annoy the hicas??
After some help, have a silver 300zx twin turbo manual,jap 1990, after driving about 6 or 7 miles the red hicas light comes on ?? fluid level ok no leaks!! if car stops and sits for 2-3min start her up and no light on !! any ideas ?????
