rev up your engines, azia says my truck runs better in the
morning when I let it warm up five to ten minutes versus when I just start it up
and go, normally vehicles don't need warming up anymore, new vehicles
they're brand new, you can start them up and then drive them away, unless you live
in Alaska it's 50 below where you gotta warm it up, that said you have an older
vehicle that's worn, yes a lot of them need to be warmed up, because the engine
is sort of carboned up inside, that makes them
have a higher compression ratio inside and let's say you got an old truck and
its carboned up inside, you're probably still using regular gasoline not high
test gasoline, well high compression engine needs high test gasoline, and
yours if it's got enough carbon is now a high compression engine, so when it's
cold and you start it up it's gonna run a lot worse than when it's all warmed up
and heated up, then it will run somewhat better even on the lower grade of
gasoline, you do have an older vehicle you learn how it works and that's where
when I'm working on my customers cars, I always learn from them and I say look you're
not a mechanic but you drive that car tell me everything about it, and I'll
talk with him for five or ten minutes before I work on the car, I'll get all
the feedback and they might say, okay yeah it's been doing this for the last
four years, then I know okay not a serious problem something that he
doesn't care all that much about and something that can't be very serious
because if it was it would get worse and worse and worse, but it stayed the same
all that time, whenever you have somebody working on your car, you always
want to explain things like that to people it makes total sense,
zroom skies hi everyone I got a 92 celica the car is having real bad
misfiring issues, what could it be exactly what it says, the car isn't
firing correctly, but it doesn't mean that it's necessarily the ignition
system, that's easier to check, first of course you take out the spark plugs if their
old worn you replace them, if you have an old car and the spark plug wires are worn
five six years old, buy a new spark plug wires, a distributor cap, a modern car 95
or newer, definitely have a scan tool hooked up, and the kicker of that is
let's say you're only having misfires on cylinder number four, well then have a
newer car that has the ignition coils built on top of each plug so you have
four of them in a four cylinder car, you can just take the number four cylinder
ignition coil and put it on the number 1 and
put the number one on the number four and drive, then if you find the misfires
have moved to number one, hey you know it's that bad ignition coil and you can
just buy the coil, it's not like the olden days, some of these coils are one hundred
and fifty or two hundred dollars a piece and you're not gonna spend a thousand
dollars buying four of them with tax when only one of them is bad, so that's
another way of checking it, but also have a problem in a fuel system that's gonna
make the car misfire, so check the fuel pressure to see if the fuel filter is
clogged, also had a problem in the engine you could have a bad valve, where you
would take a compression test of each cylinder, and if you found one cylinder
had low pressure compared to the others it could be a bad valve in that cylinder,
there's a lot of things that can make them misfire, but always check the
ignition system first cuz that's the easiest and fastest thing to check,
bushmeat says Scotty in your latest video
you said the Crown Vic is a reliable car and can last over 300,000 miles, well I have
a bone stock 2001 Mustang with 67 k on it beautiful condition, I wonder if this
is reliable since they share the same engine and automatic transmission,
yes I assume you bought it new, it's only got
67,000 miles on it, if you take care of it and drive it conservatively yes it can,
their a sports car, a lot of people drive the heck out of them and they just burn
the stuff up from over revving and driving them too hard, but if you take
care of yours and it's bone stock, yes it can last a really long time, the problem
is a lot of kids buy them, beat the heck out of them, or they keep beefing them up
they throw turbochargers on them, put on headers and straight pipes, and things
are gonna wear out faster when you do that yours but maybe you can, Adam see one cab,
Scotty my parents have an 07 Toyota Camry 2.4 four cylinder with 190
thousand miles, it gets bad gas mileage we take it to mechanics and they haven't been
able to figure out what's wrong with the thing, what do you think it could be,
it's got a lot of mileage on it, camrys get decent gas mileage especially on a
highway have a mechanic like me a good one,
road test it with his dealer level scanner when I do that, I get Live data, I get
historical data I got mode six data, when I do it and my
customers watch it just shocks them, when they see the pages and pages of
information I go through, you said that you cleaned the MAF sensor, but it just
could be worn out, and all I gotta do is driving around a little and then when I come
to a stop, look at the MAF sensor data
while it's idling, and I know what it should be, Oh anywhere from 2.4 to
3 grams per second and if it's way off I know that's bad and I'd replace it, you
can clean it but the things do wear out, analyzing the rich and leanness of the
engine, that old the fuel injectors can just be old and dirty, how to clean fuel
injectors without removal, you can watch that, have that process done, we mechanics
have pressure machines that can pressure clean your injectors, I've done that to
some and Wham their gas mileage went way up when they had that kind of mileage and
they're getting bad gas mileage, so if you never want to miss another one of my
new car repair videos, remember to ring that Bell!
