Difficulty: 0

Hello my name is Tom Brintzenhofe and I'm a Certified Master Mechanic from Reading,

Pennsylvania and today I'm going to talk to you about how to diagnose an engine problem.

In today's world with these new vehicles it is really really hard to diagnose any kind

of a misfire or engine problem without having some high dollar equipment but I can today

I'm going to show you what to look for, you know what you might be able to find before

you take it to a garage and spend a lot of dough you don't necessarily have to if you

can find a simple easy problem. The first thing you want to look at and this one is

going to be a little difficult to see but you want to check your spark plug wires. Make

sure you don't see them rubbing together. Another thing you might want to check is your

vacuum lines to make sure you don't have them loose or missing sucking air. Your wires and

everything is all hooked up in here your different fuel injectors are in here. Make sure everything

is nice and hooked up and nothing is disconnected or falling a part and having poor connections

in all your injectors here. Make sure any injectors you might see that has got wiring

hard and has got wires coming out of it just make sure they're all nice and tight. The

biggest thing is to make sure all your fluids are nice and full and just go over your vehicle

and make sure everything is in place and where it needs to be. Sometimes you get a vacuum

line that might pop off unfortunately this vehicle doesn't have too many of them but

if you look around a lot of vehicles do operate with various vacuum lines on them. Look and

listen and you might actually be able to hear the vacuum leaks it sounds like a little bit

of a hissing noise. You can just push that on and it solves your problem. You are better

off than spending $100 in taking it to the garage and having them hook the computer up

and telling you the same thing. Just basically look and listen and you'd be able to tell

a difference if you hear a ticking noise inside your engine compartment that you don't normally

hear you might want to look in that area but other than that outside of having the capabilities

of having a scanner that is about as far as you can take it with these new vehicles but

just a simple problem a vacuum hose or a bad wire or something like that will wreak havoc

on these new engines but just look around before you take it into the shop and most

of the times you can find a simple problem and correct it yourself before you spend hundreds

of dollars at your local shop. The other thing you might want to make sure is that your charging

system is working properly. You'll need your simple multi meter to check that one. You

hook it up to your battery while running. You should have at least 13 volts. Hook the

positive and negative up here and start your vehicle. You should have at least 12.5 to

12.6 on a battery that is fully charged. This one has 12.55 which is about perfect and what

you want is it has got to be at least 13. Now if you don't have at least 10.5 volts

on this particular engine or any kind of computer run engine from 2002 and up it will not operate

correctly, misfire, sluggish sometimes it won't even start but your biggest thing is

make sure your charging system is working that will itself run havoc on your engine.

Outside of that, good luck and I hope you can fix it.
