G'day guys. Below is a summary I've written up of whats happened. Bought the car from a dealer in melbourne, drove it back to sydney without issue, drove it around for a month with no issue, then; Engine light on. Intermittently on/off for 1 week, now constant.First few engine lights did not produce any symptoms, just the light. After the light stayed on for 2trips, afterengine was warm misfires started. Car has not been driven since. Started today and let idle til warm. No issues when starting except for a shortsqueal when first started, once it's warm though: Bad, constant misfire at idle. After launch / revs it misfires through til 2000RPM Between 1000-2000RPM dramatic power loss. After 2000RPM power is almost normal. Smallloss though. If turned off once warm and attempt to start again, the enginewill start and immediately cut out. Itwill stay on if revs are applied while starting. Note: this only happens oncewarm, has never once failed to start when cold. Consult port shorted for reading: Gave error code 21 consistentlyover 3 tries (diff. days) After researching here and other places (Dr. Google!) these are my thoughts, in order: - Coil Packs and / or spark plugs. - TPS - MAF - Water temp. sensor. Booked in with the mechanics on wednesday but would love to not have to spend the hundreds of dollars if it turns out to be a coil pack or something that I could of replaced myself. Any thoughts? Cheers!

Good evening all, will introduce myself properly shortly, wanted to ask your advice on something first. Recently bought an r34 25gt fresh import. Its officially rego'd and on the road as of a few weeks ago and I couldn't be happier with the car itself, but the half working, japanese reading heat unit is starting to get to me. I'm a) lazy and b) not great with electronics so was thinking a cheapish solution would be a combination of the following (head unit used as example): http://www.ebay.com.au/itm/NISSAN-CAR-STEREO-ISO-WIRING-HARNESS-PLUG-CONNECTOR-2-/250750991968?pt=AU_Car_Parts_Accessories&hash=item3a61ec7e60 http://www.ministryofbass.com.au/moshop/index.php/radio-harness/harnesses/aerpro-app8ke1-kenwood-to-iso-wiring-harness.html http://www.soundmaster.com.au/Kenwood-DPX-U6120-CD-MP3-USB-ipod-Control-Double-Din-Player/DPXU6120.asp Basically a head unit with features that I want that is not too expensive & a Nissan 1995+ -> ISO harness & ISO -> Kenwood harness. All up including shipping it will be $329 Is there anything that I'm missing? Will it simply be follow the guide on here to remove all the interior and fascia, unbolt and clip old head unit, clip on harness #1, clip on harness #2, plug in new head unit, replace interior and drive away? Seems too easy... Cheers.

Would be greatly appreciated if I could get a fast lookup on; VIN: 6U90000ER34000100 thankyou
