Are you consider yourself a handy person?

Swap the coil and see is the misfire going to follow to another bank of cylinder.

You has total of 3 coil in your engine.

Do a detail record map and switch the two coils.

A replacement aftermarket coil is oil $46 w/one year warranty and $55 will get you a life time warrent coil.

Do the swap and see what happen.

A leaky/failing injector can also cause the same problem.


Do a Chevron Techron fuel injector clean ran and highway ran.

Good luck

Codes p0300,p0302 and p0303 are coming up.Is it the plugs, plug wires or could it be something else?


Good Evening, I am sorry to hear you are having problems. Your codes in order are a random cylinder misfire, a clyinder 2 misfire and a cylinder 3 misfire. Which engine do you have in it? I would consider checking the plugs and wires if you have never had them changed. I have seen a lot of places sell a car and not change them or check them since it is running good at the time, and it seems in colder weather that plugs that arent quite up to par just wear out to the point of missing. Check those first and let me know how it goes.

Thanks

How much will it cost to fix cylinder 2 misfire?


i don't know how match the cost, but it will he you, first change the position of the ignition coil to another coil also the spark plug, read the misfire code is it P032 or replace the code, if on cylinder 2 again appear the misfire check the compression, if ok go to electrical and check wires go and from to cylinder two coil to pcm, check the ground on #2 coil, if all this ok, see the difference reading by multi tester to coil reference if all good, reprogram your pcm, or replace if necessary

HELLO,I OWN A S4O VOLVO,THAT STUMBLES ON ACCELERATION & LOSES POWER PLEASE CAN YOU HELP!!!!


the may be caused by a misfire,the first thing to do is scan the computer for any stored codes as these codes can help a great deal, so start with the scanning first, auto zone and some other part stores will scan it for free ,just write down the codes and we will go from there.

Look at the spark plug, if looks ok then that's not the problem.with spark plug out check cylinder compression if good then check fuel injector, reinstall spark plug, start engine and listen for clicking noise at fuel injector, if none bad injector replace.

Volvo s40 1.8 gdi excessive fuel consumption


You're going to have to figure out what's causing the misfire. The car is almost 10 years old, so change the plugs to start with. If you still have a misfire, go to auto zone and have them pull the codes to find out which cylinder is the issue. Then figure out fuel or spark? Coil or injector? Was there a lean code? Check for a vacuum leak. Change the fuel filter and air filter for maintanence. The cruise control may be another issue.

ENGINE MISFIRE AND SHAKING


check your wire harness on the top of the engine. Volvo must have bought harnesses from Mercedes. The insulation just cracks and disintegrates, then the wires short. Not good for an ignition system.Once they short It can fry the circuit for that cylinder in the computer. Does not set a code other than Misfire.
