it's cheap homesteading here today I'm looking at my daughter's 2010 Hyundai
Accent it was running rough and the check engine light came on so we're
gonna try to find out what the problem is so let's look p0 3-0 to misfire
detected to p 0 3 0 1 misfire detected that was cylinder one random multiple
misfires so the first thing you go to is to see if there's the wires wires and
plugs these only have coil packs is it when it on to the actual plugs
themselves so we're gonna go replace the plugs and see if these codes like
disappear okay so these four bolts that hold this cover on there's a coil that
goes on each cylinder so you put your plug in and then the coils was on top of
it so it doesn't have spark plug wire it just has coils and we check the wiring
to the coils they seem good we're gonna remove this wiring harness so then we
can remove all four of the coils we're going to change the plugs and take a
look at how everything is going then we're gonna go out and give it a try and
see if the coke comes back
you lift your little harness up and over the wait so now we're going to remove
the coil now be careful you don't break the screw off or something you push on
this little tab and pull your connector off now you lift your whole coil out so
that is your coil now we're gonna pull out the plug and take a look so we're
gonna try to do a tune up a little bit we're gonna change the plugs see how
everything looks and then go from there and I will show you the difference know
if you can see it good there is there's a huge difference in the gap distance
from this plug to that so we're gonna throw these in alright so now it's
really important when you start your plugs you don't start it with a ratchet
you just gently do it with your fingers until it'll start on the threads cuz if
you strip that in the head you're in some serious trouble and every money you
would have saved doing it yourself would then gone so just don't do that so now
you get your coil you stick your coil back in and you put your screw back on
okay plug your coil pack back in and give it a little tug after and make sure
it's actually hooked on so now continue on down the road I reinstalled the coils
I made sure the connectors are on and tight I verified that the wires look
good going into the coils so now we're back in the pack so I erased the codes
earlier so we're gonna go out and try this and see if the check engine light
comes back on
okay it is still doing it so there is a problem there's either a coil pack or
something is bad so we're gonna have to look into this farther I'm gonna hook up
the meter again and we're gonna see what's wrong so now we're gonna enter
code random multiple misfires okay so I want to see what the next one is okay
cylinder one has a misfire cylinder two has a misfire
so cylinder one and cylinder to have misfires so I think I'm going to swap
cylinder 1 and 2 for cylinder 3 and 4 and then see if they move and if it is
it's got two bad coil packs so now this should be one two three four so I'm
gonna change these for these and we're gonna see a moose the misfire moves two
three and four and if that's the case and I'll have to get two coils I'm gonna
move that one there okay that one there move these over here Sol if there is a
problem with those two coils they will technically move to 3 & 4 we are gonna
fire this up and it should throw another code because I haven't done anything
okay let it start flashing
then she's flashing we're gonna enter the codes miss fire cylinder foresee it
moved to cylinder four so we know that is probably the coil so we'll go down
cylinder four misfires so there's two instances of cylinder four misfiring
so it was cylinder one so now it's cylinder fours
we know that the wiring and everything is fine for each cylinder and it moves
that we know that it's just a bad coil so we're gonna replace it I went to
Canadian Tire and I bought a belt and the coil by wiring harness again so
we're going to remove oil number four
so there you go a nice new coil pop back in the hole
screw back on plug this back on okay let's see if the flashing check engine
light goes away normally takes a few minutes it's running a lot smoother for
sure still gotta fix that squeaky belt for
crying out loud she ain't coming back I don't think
look at that smells absolutely awful must be a bunch
of fuel got into the exhaust but otherwise gets running smooth smooth
smooth so there we go it's all fixed
