rev up your engines, Jim Bean asks Scotty my friend jump started
my car backwards and now it won't start how do I fix it, well the first thing you
want to do is fix your friend, hit him over the head or take it to a
good mechanic like me and make him pay for it, unfortunately when you jump start
a car backwards you can fry a lot of the computer system, I know a lot of people
say, Scotty well theirs fuses, the fuse will blow, well for some things like an
alternator yeah, generally the fuse a pop and it won't damage the alternator, but
computers are different, by the time that reverse power pops the computer fuse a
lot of times it will have already damaged the circuitry of the computer
because the computer so real sensitive to reverse polarity, so you can easily
destroy the computers before the fuse has even popped, now what you want to do
is of course first check all the fuses and also what's called a fusible links
on the positive battery cable a lot of times there's thinner wires coming off
and those are called fusible links and they're made so that if somebody is dumb
enough to jump start a car backwards those fusible links quickly pop before
it damages the rest of the car, so you want to pray that those things popped
and it didn't go through and ruin the computer system of the car, ESPN
says Scott I'm think about buying a new Jeep Compass with a two-wheel
drive Aisin 6-speed automatic transmission, could it be reliable, the
transmission yeah because Toyota makes them, the thing
with the Jeeps are, realize unfortunately since Fiat took over Chrysler their
control has been going down and it wasn't that great to start out with
I mean jeeps were great vehicles when I was a kid but that was in the 1960s if
you really like them, I mean at least it's got a good transmission that with
the six-speed, but still you know they're made by Fiat and their quality
just isn't that good, if you really wanted a Jeep my advice would be to get an
old one that's been reconditioned rather
than buy a new, one cuz that'll always hold its value, where the new one their
values dropped like a stone as they get to be a few years old,
hey you what do you think about buying a Mazda rx-8 I can get it
cheap with high mileage and rebuild the engine or is it expensive and don't, okay
here's the thing rotary engines have been a failure throughout history for
two reasons, one they're generally gas hogs they're tiny little engines but
they get horrible gas mileage, the original one the Mazda Cosmo in a car,
some of those things got like five miles a gallon but they could run on any kind of
fuel that was one of their upsides, the other thing is they always end up
burning up and burning oil while you're driving them, because they have triangular
rotors in them, each one has a seal, a apex seal, one two three
and when those seals go bad and they always do they burn oil, now if you can get one
really cheap and you want get it rebuilt or have a pro rebuild it or try
to rebuild yourself go right ahead, their not bad vehicles it's just that those
engines wear out fast and what I do if I were you first was price a rebuilt one
cuz theirs guys that rebuild them all the time, and if you can get a decent price
on one and you don't mind spending that money for whatever cheap price you get
it can be fun to drive around they are fun to drive, just don't think you can
get it and then put 20,000 miles a year on it, it'll fall apart again so if it's a
toy hey why not it could be fun, no user name available says, I got a 1984 Nissan
300zx turbo with 125,000 miles and a manual
transmission, I notice sometimes the rpm surges as if its
hunting for speed, any idea what could be causing this, if you're talking about
your accelerating if it surges up and down when you accelerate, the clutch is
slipping and you need a new clutch, to go to
any mechanic and they can road test it and say
yeah your clutch is slipping and you need a clutch,
now if it's not that and it surges by itself, like you're driving down the road
and you're not accelerating but going 60 or whatever it'll start going up and down
and up and down, then you got a problem generally in those in the fuel injection
system, a lot of times the mass airflow sensor could go bad or it could be that the
fuel pump is starting to go out and it has pressure, not enough pressure,
pressure, not enough pressure and any mechanic with a decent scan tool and a
pressure testing gauge can check both the MAF sensor and the fuel pump to see
if they're starting to go out mark Vega says Scotty I'm gonna get a
2006 Lexus is350 what do you think, great solid car or is it too old, my wife's driving
a 2002 es 300 and that thing is still solid, rides like a dream, it's not too old
now depending on the mileage you don't want to pay too much, you know if it's
got 200,000 miles you don't want to pay too much cuz it's a lot of mileage, but
they can still be solid reliable cars but as anything else, when you're buying a
used car find a guy like me to check out the vehicle for you, we'll put our scan
tool take it for a road test and in about an hour we can tell you everything
you'd ever want to know about that car and whether it's worth buying or not
because you can't trust anyone when you're buying a used car, except the
mechanic that you trust is gonna tell you the truth, so if you never want to
miss another one of my new car repair videos, remember to ring that Bell!
