Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / December 2006who does the free diagnostic? nissan problem (missing)
Earlier it had this problem where once I started it...within the 1st 2 miles it would want to die I remember hearing of a auto store that does a free diagnostic, does anyone know who that is? http://www.carclubsusa.com <---car clubs list free thanks for the advise. Cole That would be Auto Zone. They'll lend you the DB II Tester > Earlier it had this problem where once I started it...within the 1st 2 > miles it would [quoted text clipped - 8 lines] > > Cole CarclubsUSA.com <chilldeals@yahoo.com> wrote in article <1165980461.081060.37000@80g2000cwy.googlegroups.com>... > Earlier it had this problem where once I started it...within the 1st 2 > miles it would > want to die > > I remember hearing of a auto store that does a free diagnostic, > does anyone know who that is? Some DIY-oriented stores such as Auto Zone will plug in a code reader and download any stored codes. This is a far cry from diagnostic work, however. I doubt if most counter people in these places can SPELL diagnostic, much less do it. > http://www.carclubsusa.com <---car clubs list free > > thanks for the advise. > > Cole >CarclubsUSA.com <chilldeals@yahoo.com> wrote in article ><1165980461.081060.37000@80g2000cwy.googlegroups.com>...

O2 sensor lean indication code? Customer buys an O2 sensor after the "diagnostic." Two days later the code comes back because the original O2 sensor was truthfully reporting the REAL problem -- leaking intake manifold gasket. "EGR insufficient flow" code and they sell the customer an EGR valve. Two days later the code --caused by carbon clogged EGR passages -- comes right back. At least the "diagnostic" is free -- worth every penny it costs!

It's amazing the amount of money some people will spend to avoid having to pay for a real diagnosis.

The first time it gave me a multiple misfire diagnosis, which confirmed my fears...that the Buick plenum had decomposed and was irrigating my cylinders. The second time it was quickly recognized to be due to a gas cap improperly seated (which the Autozone counterman recognized), and we just reseated it. So for me, it has been helpful... Even if a person has his own scanner, it will only point to the codes, it wont diagnose the problem. Throwing parts at cars is a very unreliable way to fix them. > At least the "diagnostic" is free -- >> worth every penny it costs!

The scanners at my shop have freeze-frame ability, data stream readout, KAM reset, factory tests, ability to write to the PCM. There is a HUGE difference between the code reader at AutoZone and a real scanner. >it wont diagnose the problem. A scanner that is more than a code reader is frequently essential for diagnosis. Don www.donsautomotive.com > Throwing parts at cars >is a very unreliable way to fix them. Correct. >>Even if a person has his own scanner, it will only point to the codes, > [quoted text clipped - 7 lines] > A scanner that is more than a code reader is frequently essential for > diagnosis. Again, I think we disagree more in semantics than philosophy. You have commercial quality diagnosis equipment. There is a great difference between this, and what some people buy as code readers or 'scanners'. The AutoZone unit is okay for its type, but does not do the diagnostic work for you. > > A scanner that is more than a code reader is frequently essential for > > diagnosis. > > Again, I think we disagree more in semantics than philosophy.

The confusion occurs because many do not know the difference between a code reader and a real scan tool. > There is a great difference between this, and what some people buy as code > readers or 'scanners'. A code "reader" is not a "scanner." > The AutoZone > unit is okay for its type, but does not do the diagnostic work for you. Neither tool does the diagnostic work. A trained brain is still a very essential part of that step. > The second time it > was quickly recognized to be due to a gas cap improperly seated (which the > Autozone counterman recognized), and we just > reseated it. That's one hell of a counterman. ;-) I wonder how he knew it was the gas cap and not a leaking vent solenoid? >> The second time it >> was quickly recognized to be due to a gas cap improperly seated (which [quoted text clipped - 6 lines] > I wonder how he knew it was the gas cap and not a leaking vent > solenoid? He had seen it enough times that he 'suspected' it was the gas cap, but said it might be further in the system. We reseated and reset, and it turned out to be the answer. Was a service to me because I had no code reader at all. And it worked.. I dont mind taking the car to a competent dealership or independent mechanic if needed, but would prefer to sidestep simple issues like the abovementioned. > > I wonder how he knew it was the gas cap and not a leaking vent > > solenoid? > > He had seen it enough times that he 'suspected' it was the gas cap, but said > it might be further in the system. IOWs, he was guessing. > We reseated and reset, and it turned out to be the answer. AKA a lucky guess. > Was a service to me because I had no code reader at all.

And had he guessed wrong, he'd already erased important freeze frame information making subsequent diagnosis that much more difficult. >>>I wonder how he knew it was the gas cap and not a leaking vent >>>solenoid?

Although if he was wrong and the purge valve or another leak is causing the problem, the light will come back on once the car goes through the evap system pressure check again. No real harm done IMO. |
