make sure your gas cap is securely on-loose cap shows as a leak in the evaporative rec overy system - most common cause is loose cap or bad gasket on gas cap

Oxygen sensor malfunction is a common issue, exhaust side ( right side, facing front of car from rear ). You will need a deep socket to extract the sensor and can buy these for $45 - $50 on ebay, $99 at AutoZone. I use Bosch sensors only.

I have the same issue with a 2002 MR2 that i JUST bought. Check engine light came on after driving for 20 minutes. Code PO155 which indicates 02 sensor. Is this easily replaced? Are there youtube videos or other instructions on how to do this repair? thanks
