Over the months I have read loads of replies from people suggesting checking the electrical contacts of loads of different areas, most of them I have not a clue where they are or what they do. It would be so helpfull to myself and others who are new to Zeds if someone could post a photo of the engine bay with arrows pointing to all of these contacts and switches and contacts that should be checked once in a while for corrosion. Does anyone have such a photo, or could make one up. It would be much appreciated by myself (and lots of others I imagine) Thanks John

I have cleaned the throttle bodies, but sometimes my idle speed (engine completely warmed up) does not fall to its normal 700 rpm. Instead it stays at about 1000, sometimes falling to 700 or 800 if the traffic lights stay on red for a long time. Has anyone got any suggestions? Thanks John

Bought some ZYMOL CAR POLISH today - I was amazed at the results when I tried it out, awesome finish. Anyone else use it? Geoff.

Hi Folks, Im planning to do some major upgrading on my Twin Turbo in the very near future, turbos, fuel system etc etc Thing is, im a bit stuck on ECU, is there only the option of a replacement chip like SE or JWT or are there any plug in Management units that I can jack a PC onto and tune myself as and when things change? Seems a bit silly to have to get a new chip every time the setup of the car changes :S Maybe im missing something obvious here, anyone car to put me straight? Thanks Dan

havin trouble gettin air out of hydraulic system no pedal pressure at all new piston/seal assembly installed 89- na- import.

OK guys, I think this co-incides with the cold weather, but on cold start-up my vaccum is only reading around -10 psi, and then slowly goes to -18/-20 after a few minutes of idling.. (where it always used to be) If I start to drive it when it's like that it's very lumpy :( I've hunted around the engine but can't find any leaks when it happens - so any ideas? I've already got a new coolant sensor which I'm putting on in the morning, so I'll see if that helps.

What is hold/power button in my jap 300zx auto for i no this has somthing to do with the gear box but what

Does anyone know where I can get hold of a 99-spec front bumber for my Zed + the lights for a reasonable price? I think this is one of the nicest looking bumpers IMO. Cheers, Shaun

What psi should my tyres be at, I have 255/40/17 rear and 235/40/17 on the front, someone did tell me that there is sum that you can do to work it out. Twin Turbo, like the one that won the 350z on top gear, but in red. Cheerz.

just working out what I need for my engine rebuild I am keeping my auto transmission but will be using a manual engine, I know that the cam set up is slightly different and so are the turbo's . I will be keeping the manual cams and upgrading the turbo's, but when I do the upgrade will I be better to get manual or auto turbo's given the fact I will be using manual heads and an auto box :confused:

Hello all, Asking for help again - sorry! I seem to be getting a squeal now from i believe to be the rear brakes its constant when going along so I am guessing I need new pads, but from looking through the pads seem fine anything else? If it is the pads which are the best to use and prices?? Also time for two new rear tyres I have had a quote on B/S SO3 245/45/16 for 120 each or BF Goodrich for £90 each which is the better tyre? Many thanks, And hope you all have a good xmas and new year. Come on Santa bring me the 300ZX goodies!!

Ajay, you emailed me but I didnt get it - any chance of a re-email ;)

Fella's I've seen a TT 300 for sale in the trader,67k leather......manual !! in black which is the colour I'm after...it's in for £2600 as it needs a new screen....anyone know how much these cost ? Guess I could always do an insurance job on it once I've had it while...I've got protected NCB and pay the £50 excess..... Anyone know ? Ta:D

does anyone have the same problem that when you go over a pothole (and Sheffields full of em) the rear of the car feels like its on ice. It seems to skit from side to side. Its not bad but its noticeable and I'd like to know if its a serious prob. I spoke to someone the other day and he said his does the same.

Where the hell is the engine serial number -- The online manual shows it on the back drivers side of the engine but I cant see it there. Is it really there ? the picture shows an N/A engine is it differant for a Jap TT ?. If not then how the F*^k are you sposed to read it ? Any help appreciated as I have 3 days to get this car registered before Christmas else I will have to do my christmas visiting in a Vitara :( .

Info Here for anyone who wants to mess around with this: http://www.users.bigpond.com/webspace/plms/ Basically you can bulid a serial interface for the Consult port then mess around with it from code. Trying to tie it in for real time trace on mapping at the minute :D

Hi all, I'm thinking of buying a 300zx and was wondering if you have any advise on what to look out for etc..... Anyone konw of any for sale around the chelmsford area that i could go look at???? :D

Morning all Quick question (I hope). Can I confirm that the HICAS system uses normal transmission fluid? I've done a quick search and it seems Dexron III is the stuff I need. Do I top this up via the Power Steering reservoir or does it have it's own. Cheers Paul

Today with a couple of mates I'll be mostly attempting to replace the Slave cylinder, Slave cylinder hose and bleeding the clutch...praying to the car gods it all goes ok! Wish me luck fellas...:( ;) Leigh.

Hi Guys, Is this an easy job? The car came with a replacement 110 MPH unit in a box and I haven't been bothered to change it up until now. The car's a 1990 jap spec TT, so will the new unit fit directly onto the original wiring loom? Is it easy to get to/remove? Thanks Ch

1990 Non Turbo ZX Please can anyone give us some ideas as to what could have gone wrong? Car has been sat on the drive for a couple of weeks and was then driven 10 miles and put in a garage running fine no probs at all, then..... 48 hours later went to start it up and its running like a complete sack of!! It won't tick over, if you put it into gear it stalls it misses and sounds awful Thanx please dont get too technical as we are new to this

I noticed last night the power steering didn't seem as easy as it normally does,wasn't the air in the tyres and it looked like there was enough fluid in the reservoir although can someone tell me how high the level should be?

Anyone know where i can get good quality custom fit floor mats for my z? would prefer somewhere that can put a z or something similar onto them

55K miles, manual, Black met, leather, Imaculate car, but, there is always a but! I have just been for a test drive and there is no positive feel to the gear lever, it is all over the place like a van, changes gear ok just a bit vague. Is that normal or should the box be tight? Also a vibration going thru the car when driving and pulling around 3 to 5 k revs. And finally when driving along put your foot down on the gas, then lift off, then re-apply again it jerks like a bitch, any ideas, I walked away from it in the end, but if its all simple stuff then I may be tempted.
