Check for air leaks in the intake too. Could be the PCV valve is faulty, a vacume hose split or cracked, or clamp loose.

I wonder if it's something like the Cat blocked, but then it wouldn't drive very good...

I think your dealer doesn't know much about it, they should be able to fix that easy with all their resources. They can even log it with Nissan to see what they say to check.

Re: FLARING AT IDLE 1700-2500 RPM.


Hi there, I once had the same problem that occured while the dealer was trying fix another engine problem. They installed a new updated program for my ECU and the engine would flare all the time. It turns out that the fuel mapping module of the new program was incompatible with the ECU that was in my car. I had to take the car back in while the dealer contacted Nissan with details of my ECU and Nissan told them to use a different fuel mapping program. I picked up the car that afternoon and everything was perfect and has not played up since, that was about 10 months ago.

It may be worth asking the dealer to ask Nissan if this could be the cause of your problem.

Re: FLARING AT IDLE 1700-2500 RPM.


As I am now experiencing this flaring problem I thought I'd share with you how we fixed it, well about to fix it.

My mechanic straight away thought it was the throttle body sensor as he has had a few xtrails come through his shop with TBS problems.
As my sis has a T30 as well he changed parts and eliminated the TBS from the problem as is still flared with her TBS installed. He still thought it had something to do with the TBS so he moved to the pedal sensor. Jackpot!!!

It turns out the sensor connected to the accelarator is the problem (part number 18002-8H706). Typical nissan, I cant just buy the sensor, I have to buy the whole pedal assembly... and it isn't cheap.

Booked in to get fixed tomorrow, i cant wait to get the old girl back.

Good stuff Tague,

Not to confuse the TBS the Throttle Body Spacer (the performance mod we've been doing) the part here in question is called TPS (Throttle Position Sensor) emoticon

Re: FLARING AT IDLE 1700-2500 RPM.


ok so finally the problem is fixed...

My mechanic fitted the new pedal and found that this wasn't the answer emoticon his computer was telling him it was but once fitted it still was flaring.

Once booked into nissan they have re - program the computer and the problem has completely been fixed and I can report that the exy has never felt better.

After a quick phone call they have given me the pathetic conclusion that it is caused my high altitude and low temps.
Even though the previous day to the problem occuring I was at the snow, I find it hard to believe that a car that is tested in hundreds of environmental conditions before release to the public can have this fault.
 Nissan told me that although a very rare problem, it has happened to a small number of exy's in the past.

Re: FLARING AT IDLE 1700-2500 RPM.


It's probably worth mentioning that my work vehicle - BA Falcon, got a "check engine" light on the dash over a year ago. I took it straight to Ford and they replaced the throttle sensor/accelerator assembly under warranty as their CONSULT equivalent told them it was faulty, however I didn't notice any engine revs flaring/surging.

There is another sensor in the exy (am not sure if Ford has the same) it's called the (Pedal or Accelerator Position Sensor) and that could have been faulty in Tague's case as well, so replacing the pedal might have solved part of the problem, but if the TPS was faulty as well it wouldn't have helped. Nissan must have replaced them both.

It ended up that I took the pedal back and got a refund and it cost $99 for the computer reprogram.
