Laced all spark plugs and got a cylinder 1 and 5 misfire after swapping around the coils cylinder 1 stayed on

Did you change the spark plugs and correctly gap them?

Swap the coil and plug from cylinder 4 to cylinder 1 and see if the misfire moves to 1.

If it does move, then the coil or spark plug is bad. Then you can swap the coil from cylinder 1 to cylinder 2 and if the misfire moves, you know it is the coil.

Change the plug leads!

First you need to determine what type of miss you have. Is it random on all cylinders, or is it restricted to one or two cylinders? Random misfire can be caused by crank or cam sensors that are starting to give out. Single cylinder misfires can be due to plugs, wires, coils (you already addressed those), as well as internal issues such as burnt or broken valves.

Spark Plug swapping is a waste of time

You may never have a failed plug in 70 years
of driving

Now you move on to professional help

You could have failed valves,failed intake gasket
or other issues

Try swapping the coil packs around - like swap #1 with #2, and swap #6 with #5, see if the misfires MOVE with the coil packs swapped to the new cylinders or if they stay with the cylinders. If they move with the coil packs, the new coil packs are bad. If they stay with the cylinders, there's a problem with those cylinders. You DID replace that camshaft sensor, right?

Have you checked your #1 and #6 injectors?

the problem is a sparkplug or wire you must be replaced

This could be an ignition coil, spark plug, fuel injector or mechanical problem. You will need to isolate the issues and proceed accordingly. I would do some swapping arround. Swap the spark plugs 1 and 2 with m# and four and see if the misfire follows if it does you need plugs do the same with the coils again if the probles switches cylinders replace coils. if not then you may have to llok at injectors, compression and so on but I would try swapping things first

Have you tried clearing the code and go from there? Also maybe try unhooking the negative battery cable for awhile and that will reset it as well then see if it comes back to cylinder one. It's usually best to do all plugs and wires at the same time. Coils get expensive so I can see only replacing them when needed

Hi Yvonne, I'm glad to help!

The first step when you have a misfire is to see what is causing the misfire. Technicians always rules out mechanical failures before moving on too Electrical issues. What you need to do is check compression on cylinder 2 and see if its good. Remove the spark plug and test it with a compression tester. It should read somewhere around 150 PSI or more. Check it to cylinder 4 and make sure the reading are close they must be within 25 %. If the compression is GOOD then you'll need to move to the electrical checks. Here's how you rule out parts. It doesn't matter if you have plug wires or coil-on-plug. SWAP the parts from cylinder 2 to cylinder 4 and start the engine and if the misfire moves from 2 to 4 then you know its either the spark plug the spark plug wire or the coil pack if you have a coil instead of a plug wire. If the misfire does not move and stays in cylinder 2 then it could be an INJECTOR, WIRING ISSUES, COMPUTER DRIVER. As you see Yvonne it can be a lot of things that can cause a misfire. Hope this helps and have an awesome day Yvonne.

P0300 Random Misfire Detected
P0301 Cylinder 1 Misfire Detected
P0302 Cylinder 2 Misfire Detected
P0303 Cylinder 3 Misfire Detected
according to this fault codes first mark ignition coils
3 ---------------- 6
2 ---------------- 5
1 ---------------- 4
RB-------------LB
this right banks and left bank, please remove Ignition coils with lids and spark plugs from right bank and swap with left bank, if fault code change as
P 0304 Cylinder 4 Misfire Detected
P 0305 Cylinder 5 Misfire Detected
P 0306 Cylinder 6 Misfire Detected
You can Identify it's a faulty ignition system then next swap ignition lids from ignition coils be careful each coils have two lids one short and other long bit deference and when you remove and fix it to the car keep in mind correct order because each coil two different fire for two spark plugs don't mix up, if you mix it can create the fault code.if you detect any fault ignition coils or spark plugs or lids replace that and also whether god or bad recommend to replace spark plugs, find the right that's most important thing, if this way couldn't found the any ignition fault next step is check fuel presser, when the engine running fuel presser must be around 4.5 bar without engine running must be 4 to 6 bar if the fuel presser too low need to check two different things one is fuel pump other is fuel injectors, in this case you can swap injectors from right bank to left bank and find is the injectors leaking, if not leaking faulty fuel pump.is this information helped you? if yes please leave a comment,
