Sometimes the computer will have an intermittant glitch. Wait to see if problem reoccurs and monitor it based on engine start-up/run conditions. ( I. E.) Hot, Cold, Under A Load, Idling, Cruising.

Hi El Faraon,
I believe that you're dealing with 12 mm bolts and nuts....THESE ARE NOT THE SPECS FOR YOUR ENGINE, but I believe that if you use them you'll be close....Tighten in three stages up to 22nm....choose the bolts from the centre of the manifold and circle outwards until you reach the last one.....It may be a good idea to draw an overhead or plan view of the unit, marking out the bolt positions.....Start at the centre and mark the sequence and follow that....What is important is starting at the centre, so that nothing becomes warped....
Hope this helps,
Regards, Johngee10

my truck didn't do the crazy idling so much but it was running a little rough before it finnally died. it just wouldn't start back up. i changed the fuel filter i could hear the fuel pump working i finnally pulled a spark plug out and realized it wasn't getting spark. after hooking a computer module up under the dash it told me that the camshaft position sensor was out. the sensor is integrated into the distributor therefore you have to change the distributor to replace the sensor. hope this helps some, i'm actually trying to fix mine tomarrow

try disconnecting the MAF (mass airflow sensor) - it is located after the air filter, usually a black box in the intake tube. Could also be the IAC valve which monitors the engine temp, that can be disconnected but will cause high idle if removed, dont know where it is on your car though.
If the MAF is faulty, disconnecting it will make the car idle and run again, but will generate a CEL (check engine lamp) on the dash just because the MAF is not seen by the ecu, but it will run on a default map till you get another one fitted.
P0325....Knock Sensor 1 Circuit (Bank 1 or Single Sensor)
knock sensor ??? dont think this is refering to the airbag but more like a sensor to `prevent pre detonation of fuel ,check the heater circuits on the O2 sensors ,their the two wires the same colour ,disconnect the plug and see if you have continuity across these two wires ,their are two sensors on this year one before and one after the cat ,not sure what is bank one though so check all four ,cant find this vehicle in my alldata books ,diesel yes i have a customer X trail but V6 petrol i have never seen

I found after taking it to a mechanic that the timing chain, or belt after it got warm the belt or chain would loosen up and jump time, or not stay exactly lined up like they should be causing it to run bad. After it cools off, it gets back to the position it should be and runs ok for a while. Now that it is worse you can hear the chain or belt rattle inside the engine when you raise the RPM's. So the belt and the tensioner have to be replaced.
