What would cause the revs to go up and down? ive got a blowing exhaust not too bad, and when i breaked today the car started hunting, and i dont mean animals lol.:o

Connection on the temp sensor caused my Z to go hunting for revs......

 

Couldn't make it's mind up wether it was hot or cold and went up and down like you wouldn't believe!!

 

Clean the connection on the temp sensor, which can be located on top of the rad pipe behind the fan.

 

Have a look in the FAQ storage area in this thread;

 

Engine by numbers

 

HTH

 

Matty.

Geez that little bugger caused me no end of bother. Just get it replaced. About 20p (maybe a bit more :) )down your nissan garage.

£18.80 + VAT. And you've just reminded me I forgot to go and pick it up at lunchtime. :slap:

did they drop? its always possible your alternator is on its way out as it couldnt take the extra load of the ABS pump. I know if i have everything on in the car and turn power steering and apply breaks the revs drop.

 

with temp sensor error you will generall rev at 1500rpm quite a lot of the time until it reconnects and you will go to a normal base idle of 750rpm.

 

I replaced mine and now the car idles at 747rpm after she is warmed up (about 5 minutes)

ive just found out if i pull off the small hose passenger side right next to the balance bar the car runs fine could something be blocked? and can i drive with this pipe off for 40 miles as im taking it to se in the morning.
