If our climate control system is working properly, we never give it a second thought. For some, it’s just “set and forget”. For others, if the air blowing from the vents is the right temperature, it’s all good! But keeping the cabin at the desired temperature requires a complex system of electronic,…
Diagnostics

Exhaust and Emissions
Several states now require regular (annual or biannual) emission tests. These tests have different names; the most common are inspection/maintenance (I/M), SMOG, or OBD-II emission testing. The tests may involve visual inspection of certain emission-control systems, measuring tailpipe emissions at specified…
Filters

Cabin Filter The cabin filter works just like the filter for your air conditioner at home. It filters dust and dirt from the outside…
Fuel and Engine Management
Engine operation management requires the input of a few systems working together. The filtered air of the inductions system, the fuel delivered to each cylinder, and the emissions system all feed information to the ECM (or PCM) and the computer calculates the proper amount…
Hard Starting
There are many systems required for a car to start properly, so regular maintenance is necessary to keep your vehicle starting reliably. First, there are many electrical components needed to start successfully. A well-charged battery…
