Probably predictable responses from this one, but let's see.. I have in the past owned 2 300zx's, the first in 2001 (a silver 1990 TT that I paid £6500 for) that drove like a dream until I realised that the 0-60 time was not really meant to be executed on wet roads and wrapped the car round a tree. Earlier this year, with my limited budget of £3500, I bought a 300zx N/A. I bought that with a power steering problem that I wasn't able to (nor was Jeff at Zedworld, Western Auto power steering etc) rectify. The car was standard, and well,just wasn't that fast. I am currently driving a (very reliable) Escort 1400, that I bought for a few hundred quid to use as a…

Hi all, :) I am just woundering what is the top speed I can do in my 2+2 Auto ('90 UK Model). With out damaging the engine my car has had no mods except a Blitz filter. Thanks, Alastair.

Whenever i leave the car after a drive, i check under the engine & the top rad hose is all sucked in. I undo rad cap & it goes back? any ideas??

I have a bonnet vent which when it rains it drips water on the temp sensor area. After the recent rain my car have started running a little lumpy at idle. Also when I first start it from cold it idles at 1,5krpm which is normal but the fan comes on, then when I rev it a little i.e. up to 1,750rpm and the acceleration drops the fan goes off. I have check ECU codes and I got the all clear. ConZult shows a slightly lazy O2 sensor but everything else looks fine. Apart from the obvious i.e. clean/check all connectors, change O2 sensors. Does this diagnosis ring any bells ?

I have autoglass coming out on tuesday to see if they can repair my windscreen, £65.51 (im not covered by insurance) In the event it isn't repairable I've been quoted £342.60 for a OEM replacement part, Can anyone recommend a cheaper route :) (its UK glass and I want to keep the blue tint) Cheers guys.

Driving to work this morning, could not get the bloody windows to clear up. Hot air coming out of the vents though??? Just check the driver's footwell and the carpet is soaking wet and I can smell coolant. Also, the RAD coolant level has dropped dramatically and is very low. Just a hose or something worse??? :cry: Any advise would be great.....

My car is pulling very heavy to the left, now i had the wheel alighnment done and she is still pulling left could it be tyres worn un even it is jap tyres and are cracked quite a bit on one side i can't remember which side at the moment. Any idea:confused: :confused:

Hi guys and guls I have been experiencing irregular ideling on my Z. I have first experienced this when i was driving back from Southampton, when the car got to normal working temperature and i stop at trafic lights the revs drop to below 500 rpm or almost stalls and then jumps up to 1200 then down to normal, but when i stand at a red travic light for a long time the revs will drop to 500 rpm and then up to 1500 rpm continuesly untill i pull away the car misfires for a few seconds then go like hell. Could it be a leak on the intake manifold or is it more serious than that or simplier. Have anyone got some advice. Exuse my spelling i'm a dodgy South African…

I've just got new ported manifolds to go on but the EGR pipe hole has been welded over so it looks like more work to remove the EGR system? What's involved?

anyone know what the brown conector is for next to the oil dipstick? ive just noticed mine is unplugged. :confused: :confused: :confused: :confused: :confused:

Here's a wheel conundrum. "Everyone says" you should replace the J spec rears with UK spec rears. Both are 16". J spec are 7.5" wide and take a 225/50. UK are 8.5" wide and take a 245/45. The UK wheel is 1" wider than the J spec. The UK tyre should be 20mm wider (0.78"). That's the theory! In this picture, there is a UK wheel/tyre and a J spec wheel/tyre. Can you tell the difference? No, neither could I and neither could the guys at Protyre. So I took some close-ups: Tyre A is 221mm wide at the sidewall and has wear-to-wear tread of 197mm Tyre B is 218mm wide at the sidewall and has wear-to-wear tread of 199mm Which one…

Hi Guys, I did an ECU check as the car seems to be running a little on the lumpy side. I think this may be due to a lazy O2 sensor which I will change today, but I got error code 54 at 0 starts ago ??? 54 Signal circuit from A/T control unit to ECU (A/T only) The A/T communication line is open or shorted A/T refers to Automatic Transmition right ?. I have a manual ? WTF ? :confused:

I am going to be using the NA aircon fan with the TT aircon system! The fan is only a one speed fan that is due to be activated at certain temp. I believe the temp at which the fan is activated is governed by the ECU, and I will be using a TT ecu. I believe on the tt ECU it activates the fan at approx 90degrees, so am I right in assuming that this is the point at which the fan will kick in?

Ok I went out this morning, changed the rear pads and tightened the alternator belt. Car started ok, no squeall from belt. Just started the car and it died after 30 secs. It will now turn over and I have checked the fuel which is pumping out of the filter ok. I know the power transistor is a comon fault on these, how do I check it or has anyone got any other ideas to look for? Cheers Ady

The other day I decided to try this BP Ultimate stuff to see if there was any comparision to the Optimax I usually use. As I thought there was no real noticable difference apart from the price, 87.9 pence per litre! I never pay more than 82.9 round my way for a litre of Shells finest. I have also been told that depite all BP's "improvements" to there standard super unleaded it is still only giving 97 octane. ! less than Optimax. Is there anything that makes BP Ultimate better than Optimax and is it really worth the extra 5p on every litre! Anyway, starting to sound like a moaning old anorak now so will let ya guys say your stuff! Cheers, Justin

Hi, I have another MR2 question for you lot who have owned or driven them in the past. I know I should just post this on the MR2 forum but they are all useless and you guys seem alot more helpful. Its for sale anyway, Zed on its way so not a complete traitor! Anyway, to the point, I have a guy coming round to look at my car tomorrow for a second veiwing and has mentioned that he thought the gearbox was "notchy". It has always been like this and i have had it 3 years and nothing has gone wrong with the box. I assumed that MR2 turbo's gearboxes are just notchy as a characteristic . Am I wrong and will I have to chop loads of money off cos of a dodgy box? Che…

Hi guys! Is there anybody in the vicinity of Wakefield (West Yorkshire) with a ConZult who could possibly help look over a car that somebody is considering to buy? I've been asked to go over but it is quite a trek from Birmingham and I have full schedules for the coming days. Any help would be greatly appreciated. Thanks!
