MISFIRE # 1 WHAT SIDE IS IT ON WHICH SIDE IS THE # 1 PLUG ON

Standing on the passenger side.looking at the engine. Number 1 is the first cylinder on your left. Follow the wire to the coil. unplug it at the coil, lay the end of the plug close to the tip of the cap and start the engine. If there isn't multiple sparks, replace the coil. If there is , replace the plug and or wire. If you still have a misfire after that, do a compression test on number 1 cylinder.

a number one misfire means that the number one cylinder is no longer working as good as it should or is not working at all. The number one cylinder is on the back side of the engine on the passenger side. 1-3-5 are the three cylinders in the back.

Three basic things can cause a misfire.
1. a bad spark plug wire
2. a bad spark plug.
3. a bad injector.

Remove the sparks plug wire from the spark plug and remove the spark plug. Inspect the inside of the wire and the outside of the plug to see if there is any carbon tracking. it will look like black lightning bolts. If there is any carbon tracking replace the plugs and wires.

Check the spark plug gap. It should be around .060". if its over .080" the plug is worn out.

Check for spark with a spark tester.

the fuel injector is a little trickier.

Start with the things above and let me know what you find and we'll go from there.

More than likely bank 1 sensor has a possible vacuum leak, or a lean misfire on that side of the bank.(lean misfire happens when gap of spark plug are exceed due to wear), As for the 02 sensor I agree that it is reporting the true engine condition on that side of the bank

check the cylinder number 1, it should be the one that is on side where the timing belt is. I would say check the spark plug cuz it might be bad and not sparking and causes a misfire. If you got any other questions please feel free. Good luck

P0301 - Cylinder 1 Misfire Detected
P0316* - Engine misfire detected on Startup (First 1000 Revolutions) Could be a Bad Coil or bad spark plug or a bad wire on cylinder one. Check the plug and the wire first then move to the coil. Good Luck.

1-5-3-6-2-4 is the firing order.

right side is 1-3-5 left is 2-4-6

6 5
4 3
2 1

cylinder #6 is misfiring check plug(if gap incorrect can cause misfire, fouled etc) , coil on plug (or Wires) poss spark plug coil pack (check for cracks and heat damage in insulation of pack)

Firing order is 1-4-2-5-3-6 Cylinders are numbered as such: Standing in front of the car looking at the engine the cylinders farthest from you on the back side of the engine are from left to right, 1-2-3 and on the front side closest to you from left to right 4-5-6.

#1 cylinder is the first one on the front of the engine on the drivers side. the reason for your misfire is most likely either a bad plug, bad plug wire, the coil pack or all of the above

Also, Takeout #1(from front of the car on your left) and #2 and compare two plugs.
perheps #2 sparkplug is white(at contact point), Than you are in deep troble(head gasket problem, white smoke comes out of tailpipe) like I have.
