Why does my vehicle stall when at idle.


Intermittin Engine Stall
Engine No Start
Missfire
MISFIRE IN motor cylinder is more likely the cause to engine stall and hard start.
You will have to fix this problem first,
A misfire, most the time, is caused by, incorrect cylinder firing order (diagram at bottom). Or no or low cylinder compression
no or low compression is the result of A Vacumm leak.
If the timing chain was recently replaced, the valve cover had to be removed, the valve cover gasket could cause a huge vacumm leak which would effect some if not all 6 cylinders,

Symptoms
Lack/loss of power
Hard start
Engine hesitation

For Now
check firing order( coil pack to sparkplug)
check sparkplugs

NISSAN 3.5 V-6 FIRING ORDER
SPARK PLUG GAP 0.050''
SPARK PLUG TORQUE
COIL PACK LAYOUT

What does this mean cylinder 2 misfire


It means that #2 cylinder is not running right. It could be a bad spark plug, bad spark plug wire, bad injector, or bad coil pack. You will need to find out if you have spark on that cylinder. If you have spark, then you will have to check to see if it is getting fuel properly. This could also include a bad valve in the engine. If the compression is not right the cylinder will not fire either. I hope this helps you.

I have a 2002 Nissan Altima 3.5 SE About a week ago the check engine light came on, it started running rough, especially at idle. Computer diagnostic results showed missfire in cylinder 6. I replaced...


i would definately replace the coil. pretty certain that will solve your problem. do not drive with misfire or that can cause fruther damage such as catalyst failing, which is prety expensive.

Engine is misfiring. 2.5L 2003 nissan altima 130k miles. pulled spark plugs and one plug gap is smashed flat. what could cause this


one of the small screws that secure the plates to the shaft of the swirl control system inside of intake manifold mostlikely fell out and wound up in the cylinder of the damged plug causing the damage to the plug.there was a recall by nissan to remedy this by replacing screw with threadlocker.contact your local dealer for info.

Engine lopes while idling code 300 runs good driving


Hi there,

If your DTC code is correct, P0300 means: Random/Multiple Cylinder Misfire Detected.

As you have not indicated any codes from 301 - 306, then the computer has not been able to identify which cylinder misfired.

Therefore, you will need to begin checking for possibilities which could trigger the random (or multiple) misfire, which can be anything from:

- air leaks (this can disrupt readings on the engine's computer). Try spaying liquid around the inlet manifolds, check hoses etc for leaks.
- Bad coil (assuming engine has a coilpack)
- Bad or poor spark plugs
- Bad or poor condition HT leads (going to the spark plugs)
- Bad cylinder compression (compression test will confirm this)
- Leaking head gasket (this can also cause bad cylinder compression) - are you losing coolant from your cooling system?

These are just some possibilities...

Cheers,

Scott

Its a 86 nissan 4x4 with a 2.4 with 8 wires I need the firing order .


For the firing order and wiring routing2_bing.gif for the 8 plug 4 cylinder engine: (Plugs on the intake manifold side are coded "I", and on the exhaust manifold side are coded "E")

Wire to 1I should be connected to tower on the distributor facing directly to the front of the vehicle. Going counterclockwise from there, the order is (1I), 2E, 3I, 1E, 4I, 3E, 2I, and 4E.

The Spark Plugs are out of the correct order. What is the right firing order?


Ford settled on a single firing order for v6 engines covering many many years of vehicles: 1-4-2-5-3-6 The cylinder numbers are from the front of the engine left to right is 4-5-6 and the fire wall side is 1-2-3 The coil number from the front is 5-6-4 and to the fire wall side is 1-2-3. Good luck and hope this helps, keep me posted if you need more information, be glad to help
