What am I doing wrong? Cylinder 2 misfire will not go away. Tried everything. Even stumped a mechanic.


have a compression test done and look for a moving valve seat insert
it gives the knock, misfire
as it is no 2 cylinder it is mechanical because you have moved the injectors and coils , plugs and leads and it stays at no 2 cylinder
If you want clean engine oil then change the synthetic oil out and put in diesel oil 20w40
It will not harm the engine as it is the same as petrol oil but with more additives than petrol oil
it is cheaper and has heavy detergent properties that keeps the engine internals clean
from the gunk in the sump ,it is clear that changing engine oil on a regular basis is something you don't do but if you want a reliable long lasting engine , it is must do number 1

Initial start up the engine sounds like its running on 2 cylinders under powered intil the temp gauge reads normal ???? any body got the answer please


Cold starting misfires can often be caused by either tired high tension spark plug leads or ignition coil packs. If replacing leads, then replace with a full, new set. Coils can be changed individually, but it is often the case that if one has failed, then the others aren't far behind. Some cars have individual coil packs on each spark plug. Some cars have a single pack for all plugs and some have coil packs which may control two or more plugs.

To check for a misfire (ignition failure) follow these steps:

(Cold start) (Use a pair of insulated pliers)

1) Start the vehicle

2) When the vehicle starts misfiring, disconnect plug leads or coil pack connections one at a time. If the vehicle idles even more roughly, then that plug or pack should be considered fine.
Replug each connection before disconnecting the next one. Once you disconnect a plug lead or coil pack connection and find no difference in poor engine running, then you have likely found the offending cylinder. Check the spark plug condition, lead and/or coil condition and connections on that cylinder.

3) Replace components as necessary.

P0302 mis fire, lacks power


Pull the spark plug of cylinder 2. Put the coil on the spark plug. Ground the sparkplug and have someone crank the engine. See if you see a spark. If you have no spark switch coils with another cylinder. If still no spark it could be one of the wires going to the ignition coil. If there is a spark do you smell gas at the spark plug hole? Could be no fuel to the cylinder.

Computer reads misfire cylinder 2 and 6


Like Ronald Wilson said it could be something linked to the ignition ( ignition coil, spark plugs or spark plug leads ).
No injectors or oxygen sensor.

Number 3 and 4 are not firing from coil on 2002 subaru outback 2.5


its faulty coil.

Get the compression test done on each coil.these will let you know if its faulty coil or not.

=========

It can be issue with spark plugs or faulty spark plugs. Also get the compression test done for cylinders. If any of cylinder shows low compression then required, then that particular cylinder will cause misfire.

Also get obd codes scanned, the error code will let you know which cylinder is misfiring or all cylinders are misfiring.

Cylinders 1 and 3 misfiring on 2.4 Liter 97 chevy malibu


code p 0300 is random/ multiple cylinders ----misfires detected ===causes ---spark plugs ---HT lead/s---injector/s---ignition coil/s---low compression---wiring
he has changed a lot for nothing
a 5 year old engine can have a lot wrong with it --so new out of a crate is no guarantee
most misfires are from injector problems
it could be a loose valve seat insert so have a compression test done if moving the injectors to new locations doesn't move the misfire

Cylinder 1 misfire 2003 chevy impala.. My car started running rough all of a sudden today. like the engine was shaking. took it to auto one said cylinder 1 misfire. what does that mean & what should i...


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.

Missing,viborating


Misfire could be a number of things:
a) spark plugs - change them if used over 15K miles - inspect/regap.
b) spark plug wires - change them if over 15K miles - inspect
c) ECM (electronic control module) - test with HEI (high energy ignition) tester.

The vibrating tells me that the engine is running on less than its normal compliment of cylinders - the shaking is produced by the imbalance caused in the engine by one (or more) cylinder(s)
not firing at all.

The "Check Engine" light probably is coming on due the the misfire condition. Go to Pep Boys or
Advance Auto Pats, where they'll tell you (free) your codes causing the "Check Engine' light to be
lit - the code coming from your truck's computer will probably be one or more of:
P0300 - Random/Multiple Cylinder misfire detected
P0301 - Cylinder 1 misfire detected
P0302 - Cylinder 2 misfire detected
P0303 - Cylinder 3 misfire detected
P0304 - Cylinder 4 misfire detected
P0305 - Cylinder 5 misfire detected
P0306 - Cylinder 6 misfire detected
P0307 - Cylinder 7 misfire detected
P0308 - Cylinder 8 misfire detected
P0313 - Misfire detected with low fuel
