Misfire in cylinder #6. Could be bad spark plug, spark plug wire, cop coil, bad intake/exhaust valve, clogged fuel injector or piston/cylinder problem. What's the year, make, model, engine and have you been following the recommended maintenance schedule for new plugs?

What causes misfires?


If the misfire is on one a particular cylinder or perhaps 2, these issues need to be addressed and checked...
1. Power to the spark plug.
2. Coils and spark plug condition.
3. Fuel supply to the cylinder
4. Air supply to the cylinder
5. Correct fuel/ air mixture to the cylinder
6. Cylinder compression. Low compression or a cylinder compression level below spec will result in a misfire. If the compression tester shows low compression in a cylinder the causes of the poor compression reading then need to be addressed.

The fault codes generated by the computer and read by an appropriate scanner will tell you which cylinder or cylinders are misfiring.

My car is sounding like it's going to cut off and shaking like it needs gas.


Your vehicle will need to be assesed for the misfire. Most likely it is a spark plug/ignition coil to cyl2. A misfire can set other codes that will not be prudent once the misfire is taken care of

Why is my 2003 gmc v8 envoy skipping & shaking


You are misfiring. If you have Autozone (or similar) research your check engine light, they will come up with one or more of the following codes P0300, P0301, P0302, P0303, P0304 etc. etc.P0308. The P0300 code refers to "Random/Multiple misfires" whereas the other codes refer to that particular cylinder (last digit) misfire. The P0300 code sets when 2 or more cylinders misfire (can be the same 2 over and over, but it takes at least 2 cylinders to misifre to set that code. The others only take one misfire to set the code. Now that you know what is happening, here is how to fix....
Takes all to fire a cylinder (Fuel, Spark, Air & Timing) properly. If you have random or multiple misfires, it is likely something that is COMMON to all cylinders - like the air intake/throttle body area - throttle body can get carbon buildup and not open/close properly. Check the fuel pressure to the fuel rail(s), fuel filter clogged? When you turn your key to the "ON" position, do you hear the fuel pump turn on (whine) and then shut off? No whine, means no fuel pump. Check all fuses and fuse relays related to the fuel delivery system. Check the distributor cap/rotor for any signs of carbon tracking/arcing. Do you have good spark from coil? Check wiring for the Camshaft Position Sensor/Crankshaft position Sensor for timing issues. Finally, check compression on all cylinders. Need good compression for combustion to take place.

For a single cylinder (example Cylinder #2) - Easiest to check is spark. Pull the plug and look at it. Is it wet and smell like fuel? If so, then swap it with cylinder next to it. If the problem moved, then its the plug. If the misfire is still on Cylinder #2, then swap the plug wire (both ends). If the misfire is still on Cylinder #2, then swap the coil. (see where this is going?) If the plug is dry, then check the fuel injector for operation. Noid light tester or you can get a long screwdriver and stick one end on your ear and the other on the injector - it should make a steady, rhythmic clicking sound if it is functional when caricon1.png is running. No sound? Replace. Is the plug oily? Check cylinder #2 for compression. No compression or little compression means either head gasket blown or bad/sticking valve (intake or exhaust) = big money to get fixed. Timing on one cylinder is hard to test without correct test tools. Timing is likely not a problem on a single cylinder misfire. Good luck.

My car is cutting off every time im going under 1000rpm. mercury sable 2002. codes were p0301 p0302 and p0316 until i changed crank sensor and spark plugs now it says p0316 p0305 p0306.. whats going on?...


Hi

P0305 is misfire in cylinder #5.
P0306 is misfire in cylinder#6.
P0316 is misfire on start up.
Have the plugs on those 2 cylinders, and the 2 fuel injectors checked, also check for spark from the coil on those 2 plug wires.

Please get back to us if you have further query or else please accept the solution.

Thanks for contacting fixya.com

I have a 2002 Jaguar X-type. The check engine light came on and it has been acting jumpy/shaky. I recently took it to be diagnosed and the codes I recieved back were P1314, P1316, P1111, and P0302..What do...


All fault codes can be checked out at http://www.bluejag.co.uk but here are the results for some of yours. You can ignor P1111. Looks like a faulty plug or coil pack cylinder 2

Fault Code:- P1314 Indicates a Power-train fault


The fault is generally due to a problem in the Ignition or Misfire area


Fault Description: Misfire rate catalyst damage -bank 2 NOTE: This DTC will flag only when accompanied by an individual cylinder misfire DTC: P0300 - P0306

Action of ECM:- ECM Default:- Maximum engine speed reduced


After clearing the DTC, complete the Misfire monitor drive cycle
Check for a reoccurrence of fault DTC.


Possible Fault:- Cylinder compression low Worn camshaft / broken valve spring(s) Fuel delivery pressure (low / high) Fuel injector(s) restricted / leaking Fuel injector(s) continuously open Fuel contamination Fuel injector circuit fault(s) (Injector DTCs also flagged) Spark plug failure / fouled / incorrect gap ECM to ignition coil primary circuit fault (Cylinder misfire detected DTC also flagged) Ignition coil failure
Fault Code:- P1316 Indicates a Power-train fault


The fault is generally due to a problem in the Ignition or Misfire area


Fault Description: Misfire excess emission NOTE: This DTC will flag only when accompanied by an individual cylinder misfire DTC: P0300 - P0306

Action of ECM:- none


After clearing the DTC, complete the Misfire monitor drive cycle
Check for a reoccurrence of fault DTC.

My engine runs rough and the codes say p1341 and p1351


Here you go - this'll help you translate your engine codes. Looks like your getting a "Multiple Cylinder Misfire With Fuel Cut-off" and "Misfire Cylinder 5 With Fuel Cut-off". Hopefully you just need a good tune up, but this should point you in the right direction. Good Luck.

I have a misfire on cylinder 2 for an oldsmobile 6cylinder 96


i had one on # 4 and it was the spark plug wire, pull it out of the coil and if it is dark and rusty and not clean you need new plug wires

5.3 L Missing and Rough Idle Intermittently


i have a 2001 chevy z-71 5.3L. I keep getting a random/multiple misfire code for cylinder 1 . I have replaced plugs, wires, coil pack(only on #1 cylinder)., and fuel pump. I still keep getting the cylinder 1 misfire code. I put truck on a scanner and watched the cylinders. # 1 misfires at idle but quickly stops misfiring at around 1000 rpms. you can here the engine miss at idle but truck runs great on road . anyone else ever had this problem?
