2003 Toyota 4X4 Truck mileage: 79,000. My Toyota 4 wheel drive truck is running rich. It is using oil like crazy. It runs a little sluggish. I checked the injectors and they look like they are spraying about the same. Where do I go from here? HELP!

You will have to scan your computer for fault codes. We recommend buying a code scanner that works just like your mechanics. The OBD II scanner will read the data stream from your trucks computer and give you all the trouble codes that are malfunctioning. You can look up the trouble codes here. After replacing all the sensors that have failed you can use the same scanner to clear the check engine light. Check the EGR valve, it may be hanging up. Also, check the fuel pressure regulator.
