Since there have been a couple of threads recently regarding ECU checks and the fault codes they throw up I thought I'd check mine. It came up with 42(fuel temp sensor) and 34 (detonation sensor), is this bad? I've not noticed any difference in performance or any untoward noises, does the ECU store codes and then need resetting in some way or do I have an expensive problem to fix?

where abouts is the indicator relay and fuse coz mine have packed up hazards still work so i wanna check those two before i try a stalk switch :hyper:

With my orginal ECU and standard chip, I clearly have an issue with the left-hand O2 sensor, as posted before it remains static, whereas the right-hand sensor oscillates as expected. Today I fitted one of Andy’s Map 2 chips into a spare ECU and the left-hand O2 sensor behaves correctly and I have a bit better performance (no boost jets fitted yet). I damaged the standard Chip in removing it so I’m not sure if it is the new ECU or Andy’s chip that is fixing the O2 reading, but I’d suspect the ECU. Update: I've now put the orginal ECU back and the left-hand O2 sensor in now working, but not within spec, as I have a replacement I'll change it and where what happen…

Does anyone know a place where I can have my wheels re-chromed? Some of the finish is flaking off and I've been told that shot cleaning will 'pit' the surface of the alloys. I really dont wanna buy a new set of wheels if i can avoid it - all for the sake of some flaking. Any help much appreciated.

Hi. Just bought a copy of Nissan Datascan, and it shows a code 55 which is all good, but when I'm on the move the o2 sensor gauge tends to cycle up and down the gauge. Is this normal or is something not right? Rob

passing the stadium of light on the 28th, i was in my big red van, oh it was about 10.30

i've seen a couple of threads about this and i'm fairly sure i know the answer but need a prod in the right direction.the car smokes on tickover, or at lights, and i mean SMOKES.however when i put my foot down it's ok.i have read that it could be the pcv valves need replacing but if i replace these will i also need to replace anything else like the 'rear seal'? or,is it the seals on the turbos?what sort of cost am i looking at for any of these replacements? just one other question, could any of these be a reason for occasional misfire?

AHHHH the joys of motoring ,had my zed for two months so far a few minor things have gone like the alternator, turbos ,have a serious water leak and until the engine is dropped we duno where thats leaking from ,anyway few questions i need help with.The water drained out is brown,same as the leaking water whats that mean?and the oil drained out stinks of petrol whats that mean ?piston rings possibly?thanks for any advise

Just about to upgrade my ECU when I found this lead disconnected, does anyone know what it is, and what impact it has not being connected? It is next to the ECU. Thanks David

Black Z spotted round Stansted Airport. Thursday 24th @ 15.40.

Can anyone recommend a good website/supplier of aftermarket lights? I'm after some 4"-6" round fog lights for a Z related side project I'm working on. I've had a look through Demontw@ts' motorsport catalogue and there's a couple that could be useful but I'd like to check elsewhere just in case. Looking for something cheap rather than a full on race/rally spec unit at the moment. Cheers, Leigh

How long do the DVLA usually take to get your car registered? They say on theit site about 3 days but are they known to take much longer? I did a dvla search on the forum but didn't manage to find an answer. Cheers, Al

the Z has been running fine until last weekend when it developed a slight hesitation when you put you foot flat to the floor at arround 5000 revs the problem has got worse this weekend when standing still and reving the engine it seems fine but when driving the hesitation and missing now gets worse, i :headvswal t seems fine in first, then in all the other gears it gets worse now it missing over 2000 revs and drives like shite when ever the engine gets over 2000rpm!!!!!! any ideas? :headvswal

My springs have seen better days , front ones mainly, the car sits a bit low and it seems a bit firm on the ride . Would i be better off with after market ones or standard . All i want is to improve the `ride`feel and lift her up a bit . What you think ?

Hi, well after the Bolney meet (which was excellent) I drove home and my car turned itself off at a round a bout. Started easily but had a loud noise coming from engine. Had it towed home to find out that I think a big end bearing has come loose. Car idles well, no missing, just rattles like hell if I rev even slightly. Have a mechanic to help me, but I need to know if we can get to the bottom end without removing engine. Any advice would be welcome. Engine not long re built, but not happy to return it to those who did work ?? Thanks everyone. Barry

I saw this rare convertible zed outside a 2nd hand car dealership near Fazely, Tamworth. This garage has sold zed's before - at like £2500 - eeeeek!

Anyone got their boost up to 14psi without upping to a Koyo rad. Do you have any probs etc....???

Keeps bloody blowing coolant out. Just had all engine out, head gaskket done. Theres some weird little red peices of stuff floating around in there, maybe some silicone from sealing somewhere?? Topper her back up now anyway, perhaps theres still an air lock cause its not drawing fluid from the header tank, thats still full!!! Any one know where I can get a new rad cap from, could be the rubber is no good anymore or the springs lost its tension.

How do I get the cog at the front of the oil pump off? (The one that the cam belt runs on - I'm sure it has a proper name). It doesn't matter if it's wrecked as the oil pump is being replaced.

As the title really? Will any dot 5.1 do or special grades? Ive heard some banter about being compatible with the seals? Also how difficult is the ABS unit to get too?

Trying to replace the leather base on the passenger seat but not entirely sure how to separate the base and back rest of the seat. Removed the plastic covers on either side and there are a few bolts but some of them are round. Any help?? cheers ronnie

Hi all do i require a special tool to fit new bushes or can i press them in with my vice Mark :hyper: :hyper: :hyper:
