My JDM boost gauge goes from -7 to +7. Does the fact that the needle never reaches all the way to -7 or +7 indicate a vacuume/boost leak. At idle or decel it's one notch above and at full throttle it's one notch below (-6/+6?). Car seems to be running ok appart from slightly lumpy idle but it is due for an oil change and plugs. I did trawl the FAQs and other tech posts but to no avail :confused:

Picked my car up from having an oil change, drove for a mile or so, low rpm's 1st, 2nd gear. Then the car started to judder at higher rpms, so pulled off the main road but as I tried to continure the car spluttered to a halt with no power at any throttle openings and now has had to be left up a side street until I can go back tomorrow. It will still start for a second or so of very spluttery low idle, then dies. Could this be PTU symptoms? Also have to check the MAF (very cold and now splash guard, altough it isn't raining and it started fine to begin with), temp sensor and fuel (low but light wasn't on). Any other suggetions?

would it be a straight swap onto putting a J spec bumper onto a UK car?

ever since ive owned my 300 tt, the speedometer works when it fills like it. sometimes it works for a week and other it go,s up and down as often as a pair of bar maids knickers.Although it never seems to interfear with the mileage, any thoughts there? PS its a uk spec and man. :(

The Mrs loves it but it bothers me: From cold i get a hell of a vibration between 40-60mph. Ok prop shaft bearings i though. However the vibration stops after a few miles!!? Correct me if i'm wrong but doesn't grease get thinner with heat. If the bearing was buggered wouldn't it get worse rather than better after a few miles?? :)

Hi, I have recently discovered a problem with my auto box system. I have an HKS ALC fitted and it was working fine till a while ago. When I give it some, instead of the red light coming on gradually, it comes straight on. I have swapped the alc for a new one which made no difference. I have messed around with the connector for ages trying not to over tighten it in every way. I also have had a gear box rebuild a few months ago. I have also fitted a new TPS and set it correctly. Also I get a 'line pressure solenoid' warning every now and again. I don't seem to get it with the ALC and harness removed. It seems really intermittent. Nissan want £70 + vat to do s…
