I've just swapped my very ropey Cosworth for a ropey UK 300 TT, manual lol. I preferred the zx's much more modern looks and felt that I'd rather spend money on the z than on the Cossy.

 

Bit about meself - owned a fair performance bikes n cars

 

-Porsche 944, Porsche 911 Carrera, Sapphire Cosworth, Impreza WRX, 300zx , Honda Fireblade, GSXR750WT, ZX9R (which put me in hospital for 1 month!)....plus loads of hot hatches. I'm 28 btw.

 

Anyway, enough of me bragging , the z i've just got won't idle evenly, it'll hunt between 1500-2000 revs.....I haven't chance to boot it yet as I want to sort this idling problem out. Any suggestions where to start looking would be great . I have the Nissan manual so atleast I can get stuck in.

 

Cheers.

1st place to start is by cleaning the throttle bodies, and the electrical connector on the throttle pot.

I feel the need, the need for speed!

 

Disconnect the battery while you clean the throttle bodies. It will reset the ECU.

 

I has a errtic idle, after I changed my fuel filter, air filters and reset the ECU it was fine.

Cheers for the suggestions, will try them asap.

 

Also, forgot to say....there is a strong smell of petrol coming from the car once it's been running a few minutes. Is this normal for z's?

No, it isnt normal, but it is common.

 

Remove the throttle cover from the top of the engine, you will see loads of fuel lines, try tightening all of the clips. If that doesnt help then replace all of the lines, as there will be one of them with a split in, and this could potentially cause a fire, which im sure you dont want on ur new zed

Idle probs can be caused by a number of things but by looking at what you've said it sounds like the idle valve is sticking. On the passenger side, at the back of the upper plenum, you'll see a rubber hose coming off a metal pipe and bending round the back - pull this off the valve at the back and squirt carb cleaner in - don't be shy put loads in Replace the pipe and check that. Also Throttle bodies and ECU reset are recommended - cleaning the throttle bodies will wash more crap into the idle valve though
