| lol... that is the problem with these cars.... if you take it to just any garage they won't have a clue... first make sure the car has had proper maintenance. Check all the connectors you can find (some are a real pain to get off, be careful and take your time, it can be done). make sure it has the right spark plugs, check the coil packs, injectors, MAS, TPS & PTU (the service manual shows how). [ http://z32.wikispaces.com/Factory+Service+Manual ] Check the timing (with as timing light, 15 TDC), you can also check and adjust the idle..... IAA [ http://z32.wikispaces.com/Idle+Control ] [ http://www.pexcom.com.au/z32cms/e107_plugins/content/content.php?content.335 ] the unit can also be removed and cleaned but before you do that, it may not be the cause. These cars take a lot of care (remember they are old). good luck.
