Hi,

Below are the Error codes and possible solutions to them:

p0325 - Issue with the knock sensor found at the intake manifold and at the center.

p0110 - IAT sensor. This is the part that sticks to the air duck to the intake

For the above error codes check first the wiring that goes to each of the parts and the wiring harness just to be sure. Check if the connections are tight and that the components are connected properly. Have them tested. If you plan on testing this yourself make sure that you have a tester with you to check if there is voltage running.

p0306 - misfire on cylinder 6

Check the boot on top of the spark plug as this is the common failure on the spark plugs. Have it replaced. Check also the spark plug if it is needs replacement. If it has a black or white color, then you need it replaced. This could also be a product of the 2 errors above. Have the first two errors sorted out to ensure that the misfire will not come back once fixed.

cant tell you right where its coming from with out looking at it but pull out your spark plugs and if they are covered in oil it is your valve cover seal most common but if not it could be the head gasket sorry cant be more help good luck

If the Check Engine light is on, then more than likely it is a problem with the ignition coils. I30's utilize coil packs instead of Plug Wires, Rotor and Cap system. I30's had a model exclusive issue with the Ignition coils. Usually, one would go bad, and not long after, the rest would go bad, one after another. In other words it would be like having fouled plugs, which you may have also, and would create the symptom you are describing. If the light is not on, the first thing I would do is have a tune up performed. Normally on that particular car, the tune up would involve, changing the plugs, air filter, pcv,valve, resetting the idle and timing via computer, cleaning the throttle chamber, and some places would even perform a BG fuel system cleaning procedure. This is recommended every 60K miles, So if it has been a while since it has been done, or never has, it definitely should be. You could have a bad buildup of residue in your injectors and your fuel system that could be leading to this problem. In cases like this you have to start somewhere, and being able to eliminate a tune up would be the best way to begin to figure this out. 

That vehicle does not have plug wires. It uses Ignition Coils instead. On top of each valve cover, there should be three square black coil packs. They will have two screws or bolts holding them in, and a couple of wires coming out of each one. You should be able to unsnap the clips holding the wiring to each coil, Remove the bolts and lift the coil up from atop the spark plug. I would absolutely recommend Factory plugs, or NGK plugs for that vehicle. Infiniti cars will not run worth a **** with anything else in them. You will think you are saving money by putting some Bosch Double Platinum or some **** like that, until you start pulling your hair out trying to figure out why it won't run. Trust Me. Save yourself a bunch of headaches and pay a little more for factory plugs. Just try not to get the coils crossed up, they are two different part numbers. I would suggest doing the job one cylinder at a time. 

Those buttons are for you to be able to program your garage door opener so that you don't need to have to original clipped to your visor all the time. The procedure is this: 1) put the key in ignition in postition 2 (car not running) 
 
2) hold down both homelink buttons on the outsides of the homelink transmitter (to reset any existing codes) you might have to do it for 20-30 seconds. Red light on homelink will flash rapidly then let go. 
 3) Now, with the garage remote in one hand and hold the button on the homelink you want to program (keep holding homelink until it pulses, not a rapid flash, takes about 20 sec.) While it is pulsing, hold down the garage opener as close to the homeling button as possible while depressing door opener button also.
 
Shortly after doing this you will see the homelink start to flash rapidly (this means it is learning the code). 
 
-  let go of both buttons once it is flashing rapidly and 
 
4) go to motor of door opener and hit the learn button (a light should turn on)
 
5)return to the car a press the homelink button you programmed once, twice, or maybe up to three times until you see garage door open/close.

You may need to have someone help you with this procedure.

Harmonic Balancer or Vibration damper.

i need to know what part of the motor the pully came off. a ideler pully is smooth the other pully have grove

Park brake light - might mean the e-brake pedal is slightly moved down to initiate light. Battery light - means the alternator is bad or battery bad etc
may be the battery wires are slightly connected

sounds like a wiring problem unless you are a mechanic take it to a dealer

What colour is the smoke? The easiest way to check this is on first start when the engine is cold. This can give clues as to where the problem could be. is the vehicle doing anything else different? A blue exhaust smoke is commonly oil getting into the cylinders. White smoke suggests coolant getting into the cylinders. Black smoke is the engine running too rich. Blue or white smoke can often mean a blown head gasket. On a 2001 engine that could the most likely reason.

the service manual covers all that, buy it or rent it? V8 Engine. 1996 Infinity Q45 scans said it bad, if not do not listen to dweebs saying it is bad blind, not told why you want to go there at all.? bank 1, KS-1 they are both mounted to the top of the bare engine block they are Microphones, no loose bolts rattling up there or loose cam chains. the main intake manifold must be pulled. (takes skills) facing engine bank 1 is right bank, cylinder 1 front there. KS1 is on same bank. left word below means drivers seat perspective see below KS1 is on the right facing the engine clear as day we see the intake manifold is gone. FRONT Of car IS HERE X it is big sandwich, remove the top things seen to get here.called gaining ACCESS to it. KS- sensors can lie you (scannned) chain on cam bad. lifter collapsed or worse, can happen, bent valves? do you hear noise (bad) form the engine, even at idle parked. NO MAN CAN GUESS YOUR SKILLS OR TOOLS NOR WHY YOU LANDED HERE, DWEEBS ON THE WWW INTERNET TOLD YOU? but I did answer how. not tools ,just where it is and what must come off. the block. do not break bolts (snap) removing them. I use pen oil and heat and more tactics. ask with 6mm bolts, there, it can be tedious. not wrecking those. now the SM words told (pasted)

1. Properly relieve the fuel system pressure.
2. Disconnect the negative battery cable.
3. Disconnect the air intake duct from the dual duct housing.
4. Unplug the electrical connectors from the throttle body, the step motor AAC valve and the exhaust gas temperature sensor.
5. Disconnect and label the hoses from the valve cover, the throttle body, the step motor AAC valve, the EGR control valve and the air cut valve.
6. If the spark plug wires are in the way, disconnect them and move them aside. Disconnect the accelerator cable from the throttle body.
7. Remove the upper intake manifold collector-to-intake manifold bolts, and lift the assembly from the intake manifold. Discard the gasket.
8. Remove the lower intake manifold collector-to-intake manifold bolts, in sequence, and lift the assembly from the intake manifold. Discard the gasket.
9. If the fuel injector assembly is in the way, perform the following procedures:
   1. Disconnect the electrical connectors from the fuel injectors.
   2. Disconnect the fuel injector assembly from the fuel lines.

1. Remove the fuel rail-to-cylinder head bolts.
2. Remove the fuel rail assembly from the engine.

Remove the intake manifold-to-engine bolts, in sequence, lift the intake manifold from the engine and discard the gasket. see that arrow red, it is inTHERE im told Olive OyL can get there , directly./(grin)
