The "Check engine" light is the only way the computer has to tell you that it has detected a problem. You'll need to use a code scanner to read the diagnostic codes. The check ingine light is actually telling you that there is a problem somewhere in your emissions system. Emissions can be anything from your oxygen sensor to your air intake sensor and anythin inbetween. If you take your vehical to auto zone and let them check your computer it will tell you what needs to be changed. If it comes back with no codes, then they can reset the computer for you and turn off your "check engine" light. If they won't turn it off for you, then simply remove the positive battery cable for about ten seconds and then put it back on, theat should reset your computer also but you will ned to reset your radio stations too.
Engine Air Cleaner/Filter See Engine Compartment Overview on page 5-12 for the location of the engine air cleaner/filter. When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/filter at the Maintenance II intervals and replace at the first oil change after 50,000 miles (83 000 km). See Scheduled Maintenance on page 6-4 for more information. If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change. How to Inspect the Engine Air Cleaner/Filter To inspect the air cleaner/filter, remove the filter from the vehicle and lightly shake the filter to release loose dust and dirt. If the filter remains caked with dirt, a new filter is required. To inspect or replace the engine air cleaner/filter, do the following: [img]http://i45.tinypic.com/k99kl2.jpg[/img] 1. Loosen the two clips on the top of the engine air cleaner/filter housing and lift the filter cover tabs out of the housing. 2. Push the filter cover housing toward the engine. 3. Pull out the filter. 4. Inspect or replace the engine air cleaner/filter. See Normal Maintenance Replacement Parts on page 6-13. 5.

The air cleaner not only cleans the air; it helps to stop flame if the engine backfires. If it is not there and the engine backfires, you could be burned. Do not drive with it off, and be careful working on the engine with the air cleaner/filter off. Notice: If the air cleaner/filter is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner/filter in place when you are driving.
