Specifically, what information would you be looking for off of a trouble code scan? The only code I have is the P0300 but if you want more i'm not sure where to really start because it gives a lot of info that i'm not too sure how to interpret.

As far as the process of elimination work for electrical work. First you just dont go out and buy every part until its fixed as you may be replacing a $350 PCM, when a cheaper control box or part could have fixed the PCM. Then there is time and making sure you don't leave out the details. As electronics fail intermitantly and so they either performa below specification or they fail on and off arbitrarlly. A higher quality scanner will pick up other function faults with more sensitivity in changes and more informative, Also, trouble codes can come up as electrical components get out of specification. However a good gauge could tell you if that circuit with the problem has an intermittantly failing part that the other scanner did not chatch.

If I have not mentioned a site called, www. Carrepairlinks. Com.
It is a new site but has a lot of information and it has a list of the best retailers that I have worked with for the past 25+ years.
There is a retailer for every need and most of them have discounts for your parts when purchased through the link. It has some other good stuff about maintainence and product tests and Diy.
Anyway its www. Carrepairlinks. Com and is till being developed but all the discounts for our readers.
