rev up your engines I've got an easy repair anyone can do themselves in this
case it's a 2017 Kia Forte check engine lights coming on it isn't running right
but thank goodness the check engine light is on
so rather than guess we'll use a computer I hooked it up to the car you can see it
says p0301 cylinder one misfire detected now unfortunately peel codes
are going to call generic codes lots of things can make an engine misfire could
be the spark plug could be the ignition coil could be the wiring could be the
computer and just don't think it's ignition system you got a bad fuel
injector that can make a car misfire gasket intake gasket head gasket on
number one that can make it this far but the absolute simplest thing to do is
this first take the stupid beauty cover off get it out of the way and here's the
ignition coils one two three four now it says number one is misfiring so
we're gonna take that out did you thought screw it sometimes they're hard
to get out so you wiggle them they're not plug them in this case it's a dual
system you have to make it harder than normal saw you gotta click it up then
squeeze it to get it off it won't come off if you don't push that oh the number
two ignition coil get that out wiggle it pull it off get the screwdriver
I like the tab there we go then we flip it over and squeeze it off it comes then
we'll do a simple test well boot number two and a number one
all and number one and a number two all put the bolts back in yeah I'm not sure
they're lined up they got to line up with that hole and get them snug and
remember to plug them in this one plugs in here snap there's some plugs in there
we'll leave the top off it's just a stupid beauty cover yeah well just push
reset on the hand tool and that resets it so there's no coach then we'll take
it for a little Drive well I Drove it around the light came back on so that's
good now we can check it so we'll plug the working end in
again here we go see what going on there it goes gonna read it well it's got one
code p0301 misfire cylinder number one so it's not the coil
cuz it's still not firing right well guess what now we're back to square one
but at least we didn't waste any money we swapped the cause but the misfire
stayed where it was originally so it's not the ignition coil so put the coils
back take the other one so we're gonna check the spark plug and lo and behold
the spark plug is loose it's not in tight enough I'm gonna check it out
anyway it doesn't look bad but who knows since this one's loose we're gonna check
them all and I'll probably replace them anyway
take them all out see if any of my loose roo loose and put it all back together
and see what happens next year I played on the right hole this is the green one
that's number one and now we're missing one there those there's number two and
we'll hook on the cables up run to those we didn't unhook and then we're gonna
bolt them all back in oh four on them don't start her up against see what
happens
well it's running good now so we'll take it for a road test and see what happens
bad now I'm back it's running fine no check engine light it did put in for a
new spark plugs the old ones had gotten loose but got 80,000 miles I put in new
spark plugs no more misfiring and you might wonder
why did it only have a misfire on one cylinder and not all of them if the
spark plugs were worn out well even off the machine things don't necessarily
wear evenly in this case the number one spark plug got looser and wore more than
the other spark plugs did but you're gonna change them change them all don't
go through the trouble of guessing here and there change all four of them make
sure they're nice and snug so they don't get loose again and it won't have
misfires in this case just a misfire on one cylinder not on the others
eventually you probably would have done them all but we want a fix car so when
you fix them fix them right ones bad change them all and here's some bonus
questions and answers Gary 23 says what's the craziest customer you've ever
had this woman that I had years ago I worked on a car and then she didn't like
it because she took the car to the dealer and they said oh well he
destroyed your car so I said what do you mean is it working oh it's working fine
but they said you destroyed my car I'm like it's working right I fixed it
and they wanted 2,500 bucks at the dealer to fix it then I fixed it for
five hundred of course you know she was a little on the crazy side so I just
said okay I'll give you your money back your five hundred bucks so I gave her a
check and I get a call from my bank and the bank says this lady has checked that
you wrote to her but she refuses to sign it to endorse it and I said well I know
she's a little on the crazy side but didn't realize she was that crazy they
told me that she said she was worried that I was gonna get her signature on
the check that I get back like I guess she thought it was some kind of voodoo
doctor but if I had her signature I could do something to her I don't know
but that was hands down the craziest person I ever dealt with in the car
repair business and lead us to say I never tell what they're getting
Rodriguez 95 says Scotty I wonder if you have a clue what's going on every
morning I start my 2016 Nissan all make some rattle for something seconds
and goes away odds are you got a problem with your timing chain a lot of
times the tensioners don't work right when you start your car up of course
everything's got slant because there's no oil pressure well the timing chain is
pushed in by the tensioner that uses oil pressure and when they age a lot of
times they'll rail right on sign up and then stop doing it have a mechanic look
at that cuz if that is the case it's best to fix it now before something
breaks and then the timing chain slips and then you're really up the creek
without a paddle it might need just the tensioner you can have that done I have
the chain check too because if you got a lot of miles sometimes I stretch and
then you got to replace the chain but get it looked at because you don't want
that chain breaking on an interference engine like that it cost a fortune or if
it breaks it'll christens lit the valves and pretty much say goodbye engine
Toyota Honda 1999 says I got a 99 Civic 5-speed with one hundred and forty five
thousand miles when I shut it off it makes a weird noise every few minutes
for about 20 minutes it's quiet but noticeable well I want to hear the noise
so you can make a video I'll listen to it go ahead and post it if it's like
little crackling noises that's the exhaust system it gets hot as it cools
down I'll often make clanking noises now if it's not that and you do hear some
noise here's something you can try us open the gas cap take the gas cap off
listen inside if you hear it in there it's the fuel pump sometimes as they age the
system's get a little weird they send power to the fuel pump but the think
will be turning itself on and off and if that's the case you could have a bad
fuel pump relay or they have a bad ignition switch lots of things can still
send power to the fuel pump but make a video let me listen to it because that's
the best way I can tell by hearing music son Scotty I got a 96 Volvo 850 285,000
miles whenever I'm at a stoplight the engine rumbles loud to the point
interior shakes any ideas okay that thing's old as the hills you want
to start with the basics check the spark plugs the air filter funny that's one
then listen for vacuum leaks your air socket that'll make it Rumble too also
check the motor mounts it's got two hundred eighty five thousand miles
you're stopped and it's rubbling in drive but you put it in neutral and the rumbling stops
that's often just the transmission has worn the torque converters worn and it
strains the engine too much and then that
they say if you can ship to the neutral stops rumbling do that for a while I got
plenty of customers do that with older cars often where internally you're not
gonna rebuild the transmission put a torque converter in for something that's
just shaken when it's got two hundred eighty-five thousand miles but check all
the other stuff first tune-up vacuum leaks motor mounts could easily be one
of those two well if you think speeding and car skills you're right and you
might find it interesting that the top most dangerous place that you're gonna
get killed in a car wreck I'm not necessarily the biggest city out of the
top 15 only one of them has more than a million people guess what the top one is
north Las Vegas Nevada well isn't that a surprise that comes
Irving Texas just outside of Dallas I always say people in Dallas drive like
maniacs dad of all things comes Cleveland Ohio then Fontana California
in Plano Texas Washington DC comes up on the list how there's in Cleveland
relatively wide open I guess you can go a lot faster you get in more wrecks it doesn't
have anything to do with the snow versus ice cuz there's warm places on there
there's cold places on there it's kind of interesting to see which places are
the most dangerous ones to drive I'd expect chicago that's on the list to
Charlotte North Carolina well I got to see that because I was there a few years
back it's got gridlock really bad and people drive like maniacs there it was
taking an uber and the guy happened to be in a Nigerian driver but he been here
for like 17 years on the highway he'd get off at the accident but wouldn't
take off and then it come right back on on the merge sunny other side and people
were honking to beep it I didn't care the people there were I mean it was a
madhouse doesn't surprise me there's a bunch of people dying in car wrecks in
Charlotte because of the messy traffic situation it's a half when they get a
chance to go fast they do I know that from experience
