Why You Should Never Get A Diagnosis At The Parts Counter.
video description
I know you have a video about all the various ways and scantools used, but I just can't recall the last use of the Toughbook is what got me wonderin'. Thanks whether you answer or not, appreciate your teachings with these videos! Need some brake job videos soon. :D

Hey Eric, so I hope you re able to find some time to respond to this because I m at a loss with it right now. I own a 2001 Chevy Silverado 1500 5. 3L V8. So it was originally running a code for high fuel pressure and would misfire randomly and so I changed a coil and fixed the misfire. But still randomly start to bubble it sounded like when you would give it gas to go but would go away after driving for a minute or so. Then I put in the charcoal canister both canister vent valve and the solenoid and the fuel pressure sensor. I even put it in the shop for a week because it still randomly after warmed up start to kind of rough idle. But they put 150 miles on her in a day and it didn t do it once and the high fuel pressure light is gone and isn t back on. But today it felt shaky and that bubbly feel came back. If I it off and cool it down it goes away or if I m driving it for a minute or so it clears itself. So could you have any idea what could cause it?
Love your videos always so helpful

I would love to just send my vehicle in to a shop to fix a check engine light. The problem is that shops rip you off and tell you horror stories. I go on line and research whatever the parts store guy says the code is and watch shows like yours to try and fix it myself because I have very little funds. Hell, I went to get an inspection sticker and left with a huge exhaust leak and minus 150 dollars plus the 35 dollars for the sticker because he said my flex pipe was bad and gave me a rejection sticker. Then he said he could fix it for 150 and give me a good sticker so I let him. The weld broke on my way home. There was never a leak, he just wanted all my money. I brought it back and you should have seen the booger weld hack job these tow heads did on my truck.

5-6 years ago when i had no wrenching skills, I had a starter heat soak issue. Gecko mechanic i hired of craigslist, removed the starter and took it to oreillys for a bench test. It passed the bench test. he place it back into the car without troubleshooting furture and trying to fix it. After struggling with it, i decided to take up wrenching, Now i drive luxury used cars and swap those every 6-8 months. Fix them up for fun and sell them after getting bored. I dont make a profit but i have satisfaction that next guy got good car from me. i am wrenching myself now because of that experience. its hard to find a mechanic with scope skills.

Thank you. In our world as old guys when you got work you did a good job so that customer would tell 5 friends you were worth the money and you get more business. Today they are just wanting to screw you and the next guy. They do not care about return business. Bravo sir. Your integrity is unbroken after years of watching. You are a great man husband and daddy. Kindness is a weakness to the indecent but virtuous to the decent. Your one of the decent ones.

As a former manager in an auto parts store that did read codes, I ALWAYS told customers to have an actual diagnosis done before replacing parts. It clearly says on the top of the printout The most likely cause. Doing the actual diagnosis to find the failure is necessary, but some people would just throw parts at it and then be very upset when the light stays on. Reading codes is not diagnosing the problem, it just tells you the code.

As a person who works for one of those auto parts places that does the free check engine light scan I really wish we didn't. Because we're pretty much told just to give the customer the code, and to recommend they take it to one of our commercial shops. So then the commercial shop is going to scan it again any way then properly diagnose it. So it really renders the whole point of scanning a customer's car pointless.

Had an AutoZone tell someone that they needed a new ECM because of a short in the CANbus wire in the driver door boot. The big box auto part stores are also great for telling people they need an O2 sensor for a bad catalytic converter. I have told plenty of people to bring their vehicle to the shop for a proper diagnosis when they come to me with a paper from a part store diagnosis.

Even though I will never back off about mechanics with soldering irons, this one is beyond spot on.
Troubleshooting is a dying art. Beyond that though, most people can't grasp the difficulty that arises when you tell a customer he needs an expensive part and that doesn't fix it.
You shouldn't buy any damn thing until you know WHY you are buying it. Period.

Yup take it to Advance auto parts where they don't want to hire any one that knows anything. After I retired from 45 years in the automotive service business. Where I accumulated over 4000 hours technical training and 500 hours management training. I applied for a part time job at advance auto and they said I wasn't qualified to diagnose vehicles or sell parts!

Just outta curiosity, when you killed number 1 and it disappeared from the graph, could you have used the firing order to determine which injector was drawing less amperage. I know that it's easier to just shut off the injector, but could you use the firing order to determine it also? I'm not criticizing in any way, I'm just trying to learn. Thanks Eric.
