At Big Dog Diagnostics, we offer a unique, specialized and more personal automotive repair experience. Has your mechanic ever told you, “it needs to go to the dealer..” That is not in our vocabulary. We Specialize in diagnostics and programming services. However, we do offer a wide range of routine maintenance and repairs as well. As well as being the only shop in Spokane to be offering board level repairs to damaged electronics and modules
. We also believe in non-intrusive testing methods. This allows us to access difficult or fragile parts and test them before removal. In the image above you are looking at all 8 ignition coils firing on a ford 4.6L engine simultaneously. With this data we can see 2 weak coils. We were able to quickly analyze the data and get this truck back on the road! When dealing with a tough misfire condition it can be hard to pinpoint the failure item as there are a considerable number of different items in the ignition system. Our testing methods will save you a ton of money in the long run! We test and verify before recommending anything.
