Plugs are sparking on the four plug wires after putting new valves

Connecting new spark plug wires on your Renault Kangoo II 2010 (4-cil 8v petrol) can be a bit tricky, as the correct order and routing of the wires is important for the engine to run properly. Here is a general guideline on how to connect the spark plug wires:

1. Locate the coil pack. It is typically located near the engine, and it is a rectangular housing with four spark plug wires connected to it.
2. Remove the old spark plug wires. Carefully remove the old wires from the coil pack by pulling them straight off.
3. Label the wires. Before you remove the old wires, it is helpful to label them so you know where they came from. This will make it easier to connect the new wires in the correct order.
4. Connect the new wires. Carefully connect the new spark plug wires to the coil pack. Make sure to connect them to the correct spark plug tower on the coil pack, and route them correctly.
5. Start the engine. After connecting the new wires, start the engine and check for any misfires or problems.

It's important to have a good understanding of the engine and the spark plug system, and to be familiar with the tools and materials needed to do the job properly.
It's also important to refer to the vehicle's service manual for specific instructions on how to connect the spark plug wires, as the order and routing of the wires can vary depending on the make and model of your vehicle.

The spark plugs are located under the four spark plug wires that go through the middle of the valve cover on top of the engine. With a twisting motion, remove the plug wires from the spark plugs. Then using a 5/8 inch spark plug socket and inch extension on a 3/8 inch ratchet, remove the spark plugs. Gap the new plugs to the correct gap (located on the label on the underside of the hood), and in stall into the holes in the valve cover using only your hand to get them started, then tightening with the ratchet. Then reinstall the wires back to their original locations, and you are finished.....

simple if you are familiar with engines remove 1 spark plug wire at a time unscrew spark plug replace with new one put wire back on that plug and continue to the next wire remember do one at a time should only be four plugs on that vehicle

Try switching the ignition coil with the other coil and plug it in and check for spark again. If it works in the other coil location, then you need an ignition coil. Your engine is bad for valve cover gasket leaks which deteriorate the spark plug wires, so if you are going to put in plugs and wires with the new coil, I would recommend replacing the valve cover gasket and spark plug tube seals(included with the valve cover gasket set).

So your codes are: Multiple random plus misfires on 1,4,8. Misfire during startup, and ignition coil E (cyl 5) primary or secondary circuit malfunction.

You said that four new coils were installed. Perhaps the coil to spark plug order and the firing order have been scrambled. The spark plug wires may be old and leaky--especially if they are the originals from 2003. You could have a vacuum leak into the intake manifold, the EGR valve could be sticking open when it should be closed, the fuel filter could be clogged, the fuel pump pressure could be too low or stuck at the idle setting, the fuel injectors could be dirty, and cylinder compression could be low (putting on the wrong size o-rings when reinstalling injectors will prevent proper compression.)

Yes. The valve covers have seals that seal around the spark plug tubes where the plug wires go down through the valve cover. A valve cover set should come with the spark plug tube seals. This is a common problem with Honda. I also recommend replacing the plug wires because the rubber boot can get saturated with oil and cause a misfire. Sometimes it may look like the boot is clean when you wipe it off, but the oil is still in the pores and can cause the boot to allow the spark to arc over to the spark plug tube. Most of the time the ceramic on the plugs gets messed up also. This can also cause a misfire. If the plugs have any brown or black discoloration that does not easily wipe off with a rag, then I also recommend replacing the plugs. The discoloration is caused by carbon. Carbon is highly electrically conductive. This will allow the spark to travel down the side of the ceramic to the metal base of the spark plug.

Check the firing order tu might have installed it differently, clean the Hi-TENSiON wire terminals on the distributor cap and to spark plugs, oxidation makes contacts to these points might have attributed to the problem! The oil must have leaked from the o-ring seals around the TUBE where u put the spark plugs! It also makes the spark plugs misfires! Replacing these o-ring seals, u have to pull down the valve cover, u will see the rubber around the tube, pull it off and replace w/ new one, clean the area first and put a little silicone sealant! Put everything back! Thats it! Taaah!

There may be an engine cover over the valve covers that is a big piece of plastic that may say Hyundai, or Santa Fe,

I believe its three or four 10mm retaining nuts that hold it on, take that engine cover off, and there should be 3 wires in the top of each valve cover, those big wires are the spark plug wires, and they actually connect to the spark plug which is down inside the cylinder.
To remove, you will need a 3/8 drive ratchet, a long extension, I would say 6-12 inches, long enough, but not too long, and a 5/8" spark plug socket.
Take one of the spark plug wires out, and put your long extension with the spark plug socket on it down into the hole that the big wire came out of and you should find a spark plug at the end of the tunnel.

The po301 is a misfire code. The backfire can be caused by a excessive amount of fuel, bad valve timing etc.
My guess is you have damage to an exhaust valve that may have occurred when you had the timing belt problem.A compression test will indicate if you have a leaking exhaust valve.The reason for the backfire is the exhaust valve is still partially open when the spark plug fires.

did you try changing you sparkplug wires?


hopefully that fixes it.
