I'm not sure exactly where the PTU is (or exactly what it does) but from searching through the forums it appears to be a trouble maker. My 300 is missing at low revs (up to about 2.5) but smooths out at higher revs and seems to run ok. If I floor it at high revs, no problem. Down low and it sounds like poo, like it's missing on one of the cylinders or running really rich. I took off the coil packs on 3 of the cylinders (one at a time) and fitted a spare plug. All three of them seem to fire ok but miss every 8 or 10 or 6 sparks. Any ideas...? (the other 3 coil packs are under too much stuff for my limited skills...I think) BTW, this started happening AFTER I …

Check out http://www.jiperformance.co.uk/New_Folder/home/product.htm Half the links don't work but the Blitz, HKS & Apexi links do. They have some bargain boost controllers, especially the Blitz SBC ID-III for £350 inc VAT! That seems very cheap. Also the Apexi AVC-R is only £330. They're asking the same sort of prices on E-bay! Or is there a catch :confused: Shaun

Is it wise to disconnect the 6 coil packs one by one to see if engine revs drop while car is running? my mate has just done it and said when he disconnects no 5 engine note does not change hence not firing? Ta

managed to run into a speeding boulder today or it sounded like that anyway have got small dent in windscreen just smaller than a 5p but is almost in line of vision so think its a replacement job, is there any differences between the uk and swb windscreens or anything else i need to mention when i try and get this sorted out??? darren

I removed the mudguards off my Jap spec last week and have been left with thick sticky pads on the rear bumpers. What's the best way to get rid of them without damaging the paintwork? They're stubborn ****ers.

Lovely white zed heading East between Southam and Daventry at about 8:15 this morning. Vented nose panel and high rise spoiler :cool: Was it you? :cool:

Spent the whole weekend working on the car. Did timing belt and HICAS removal. Now the bloody thing's rewarded me by detting like a bugger. Guess what ever was wrong at thor has got worse. Even pings at 3500rpm with a JWT map!! Guess that's another weekend of checking for fuelling probs and air leaks then :mad:

Hi all, I have now noticed another noise coming from my Zed. I am getting a tappety noise coming from under the car. Its definetly not from the engine as it is coming from something about half way along the car. I am still getting this wurring noise from the rear and a vibration through my seat. Is it likely that all these things would point to a faulty prop centre bearing? I was unsure before but now I have this new noise surely this can be the only thing? Cheers, Justin

I have an intermittant missfire. I was driving down an a-road the other day and it started missfiring really bad so I pulled over and had a look. All relevant plugs connected. Drove through a 30mph village and out the other side. Still doing it after a good caning. Drove through a 40mph village and it cleared. After a couple of weeks it came back yesterday. Driving along a-roads and after about 5 miles it was missfiring for about 15 miles then mysteriously dissappeared. Have cleaned out injector and plug cap connectors about 2 weeks ago. Not cleaned tps connector but checked CAS and PTU connectors which seem fine. Temp switch connector seems dodgy and not cleaned ou…

What i meant to say was 8x19 8.5x19 allround front and rear sorry had the mrs bending my ear

Hi everyone could anybody tell me when fitting aftermarket wheels do the Back rims need to be wider than the front like the originals or would for Example 8x19 8.5x19 be ok. also what offset are zeds Thanks..........Ian :dance: :bow:

Just a quickie, Im interested in the new bumper from Luke, but think a number plate might spoil the look. Whats the law regarding number plates, I wondered if a near horizontal one would be legal fitted in the marked section on the pic, bit like they used to have on the older classics, possibly stick on plate.

Where can i get one from and any idea how much they are. cheerz, mickey

Here's a pic of me fiddling with pipes this afternoon... driver's side. http://rides.300zx.co.uk/rides/1982/intake-wtf.jpg Two questions about the hose in my left hand (oo er), which was previously joined to a small pipe underneath the middle pipe on the right... (the top pipe is coolant, obviously) 1) It runs toward the back of the engine and disappears... by having a good nosey I can just see it joins some sort of t-piece. Is there ANY chance I'll be able to change this with the engine in the car and without a ramp? 2) Were the boost jets meant to be in this line? Because they were. Incidentally, the "adjustable" boost jets I inherited aren't ro…

been changing all my boost pipes think ive changed the ones with the mig tips in but cant find them in the old pipes am i being stupid or could they have been pushed somewhere steve

Anyone know what this is? Its on the bottom of the steering rack, and has anyone got one to sell? as the wires have come off mine!

My rad looked a bit low so I stuck in about half a litre of anti-freeze. I then ran the car in the driveway for twenty minutes or so and when it had cooled down (after reaching a stable temp and with heat coming out of the matrix) I checked and it needed another half a litre. I'm thinking air lock somewhere in the system. I've parked so that the rad is at the highest point of the system - are there any bleed valves or tricks I can use to ensure that I've got all the air out? Cheers.

as above, anyone done this.. is it a particularly hard / easy job to do! does it need to be on a rack or can i jack the car up and take wheel off and do it that way? any advice! cheers Matt

hi, everyone, there is another question for all of you again; :tongue: I haven't drive my z for about a week, and now I can't even start the engine, I tried to start it up by connecting the battery to another car's battery, but it seems useless, and nothing I could do with it, any idea? Thanks for all of you any advise appreciated

hey everyone! already did a search and have rang bout 8 companies so far, noone will insure me! th one quote i did get was over 3grand! am 20, 1yr ncb, live in leicester, got a jap TT auto. is there anyone on th forum who is 21 or less who is paying less than 2grand insuranc? please help! :cry:

Hi all, Does anyone know where I can get the above (pref. from within the UK) and approx. how much ££. Found a source in the US but they have since disappeared ... Thanks for your feedback.

My heater matrix problem is now so bad it looks like my car is on fire when driving. Both windows are down and shes pumping out loads of evaporated antifreeze. I have been advised to try something called Novastop . It works by thickening up the coolant. Its supposed to work and dosent damage the internals like rad weld. Any thoughts?

as above, need a uk chassis number to get a price of a part from nissan A.s.a.p please need this urgently! Matt

Anyone know the correct procedure for bleeding the PAS, and what the nipple is for. It's next to the HICAS Solenoid (or the big space where mine was :) ) All I did was spin the wheel left to right loads of times and keep topping the fluid up.

Can someone reccomend some front pads,not too expensive but one's that don't squeak?????
