Emission light came on and car seems to be a little jerky - drove around the block and came home when saw emission light (had to look in manual to see what the light meant). What are the possible problems & solutions - would like to know before taking car in to get repaired. Thank you.

Some possibilities are the egr valve, is faulty, the oxygen sensor is faulty. The catalytic converter may be clogged. This can also mean you need to service your emission system which means if nothing is wrong to simply reset the light here is how.

DESCRIPTION

Some vehicles may exhibit a MIL (Malfunction Indicator Light) with DTC P0442, P0455, P0456, P0457 or P1442 or a Check Fuel Cap light illuminated with DTC P0457. These conditions may be caused by loose or leaking fuel cap or leaks anywhere in the evaporative emission system between the fuel tank and the engine.

NOTE:

Testing procedures described in this bulletin use the Mazda Evaporative Emission Tester P/N 134-01049. When using another tester follow the operating instructions for your tester.

Evaporative leaks may be caused by a loose, dirty or faulty fuel filler cap. Do not clean or replace the fuel filler cap until positively identifying it as the source of a leak through testing.

Check out the diagrams (Below). Please let us know what happens.
