Hi Finally Got my new dump valves fitted tonight:D Sound awesome when they go off:hyper: Anyways, this has never happened but thought it was coming. When the car was left ticking over itself it seemed to sound like it was ready to stall on itself, but would kick into life. Then when driving it tonight the car cut out on me when i stopped at traffic lights. Was told by my mate who was in the car to have my idle control valve checked first then my leads and distrubutor cap. Was wondering if this is true and if anyone else has had this problem. Also if this is to be done what would it take to do it? be put in a garage? would it be expensive? Chee…

Hi ive just bought a 300zx twin turbo and just got a tacho with shift light. Can someone tell me what the optimum RPM to set the shift light at. Thanks in advance and hi to all the members. Gonzo

and hesitation when coasting, like its trying to go then stop when coasting in gear if ya know what i mean any ideas more so when cold

When running about 20 - 25 psi, what is the recommended gap on the spark plugs?

Also, how do I check them and how do I clean them up? I am running rich. Second question: Is the engine coolant bottle on the left at the front supposed to spew coolant all over the floor when you top it up (from somewhere about halfway down the bottle), or does mine have a crack or hole, i.e. is it supposed to be sealed? There doesn't seem to be any cooling problem and no coolant seems to be lost. PS - one other thing, the dipstick in the coolant bottle has suddenly started developing a black smudge at the bottom. I thought about possible blown gasket but that doesn't seem to be the case and there is no engine warning light. Thanks.

Hello Folks Im guessing this will get a good few people reading it because of the title.lol. But Anyways...... When driving the car, when the engine is cold, i have found that if sitting at around 40mph in 4th gear and allow the car to slow down itself to just under 30 it starts chugging, as if theres not enough fuel getting through or something. Not to sure of the problem, just wondering if any of you guys can help? Cheers Craig

Firstly, it seems on of the wires at the dett sensor conx is well not in the clip ??? i'm sure i read somewhere that this is normal????? secondly, changed my plugs to 11b now the ones that came out turned out to be for a GTO and have a much shorter thread travel, is this gonna have caused damage as the ignition will take place higher up near the valve seats??? 3rd, whats the best way to get on the top bolts to the down pipe on the drivers side, one is not fully in, ive tries from the top of the engine with various extentions ans so forth but no joy. 4th, is it possible to release the wires from the coil pack conx as i have six new ones, and i dont really wa…

Hey all, I bought my lovely Zed in a bad way, some fool tried to do stuff to it and ballsed it up. I got it with only the exhaust down pipes and back boxes, no mid-section, but it came with a de-cat pipe. But, there are two cables under the middle of the car that have been cut, that I think were gas sensors going to the cat? And when I drive it and give her a few revs, a warning light flickers on and off on the dash, the red light looks like a cat with 3 heat wave lines coming from the top of it, what does this light mean? It could be possible that the cables are shorting out, as they have been cut very sloppily, I'll sort that tomorrow. Are these essential things that ne…

Hi guys just a few wee ?,will a 1991 n/a auto engine fit straight into a 1992 n/a auto. And i have notice that my car will not rev over 5500 when driven,is this due to the fact that its a auto,or is it because it has a restriter on it or is there another reason.:confused:

Had a search through the topics and there is a lot of mention of leaking fuel lines or the O2 sensor but my problem seems to be straight suction of exhaust fumes in from the back when the window is down. Strangely (or possibly not) this seems to have started up after I had a spot of how's-your-father with a tree and had to have some panel beating done to the right rear above the wheel. Also installed a new aerial and right rear light cluster. Are the exhaust fumes coming in through (a) the seal between the hatch and the body, (b) the light cluster, © the hole where the aerial exits (I see there is no o-ring there), (d) all of the above or (e) somewhere else? …

I'm seeing loads at the moment! Uk rear bumper. Just seen it at the services. Looked very nice.

thaught id start a new one, ripping off the thread "whats the mod you most regret" what mod do you regret not doing sooner? money the only issue creating the delay :smash: Boost up? intercooler? clutch? what mod you glad youv done? :)

Hi all, I've got the old error 34, although I haven't yet found whether it is the sensor (most likely) or the loom after it, I was wondering which is the best route to go down, re-location or by-pass... Obviously I would want to re-locate it or replace, but I have heard that alot of aftermarket ECU's don't have safety maps, I have a Mines ECU, is it worth shelling out for a dett sensor, or would bypassing it be just as good? It is bypassed at the moment, but only temporarily, as I've just finished the re-build, so wanted her to start up proper etc. The other thing is, my (stock) boost gauge isn't working, and haven't ever driven one of these before, cannot tell if it…

Hi all.. Tried to start my imported 1990 non turbo 300zx tt on Sunday but it would not fire, the engine just turned over. Car was running fine and the only thing I did on Saturday was to change the dipped headlight bulbs, but 1 had blown again come Sunday! Got roadside assistance out who found there was no spark from the plugs so said it was an electric problem, possibly a sensor issue but also said although unlikely, the blown bulb could have upset the immobiliser?? Has anyone else had this kinda trouble or knows where I should go to get the car looked at? I'm from St Albans by the way and any help you be most greatfully recieved!! Toby.

Where can i get performance radiator hoses as mine are starting to perish, i also have a larger uprated radiator if that makes a difference:D
