Hey everyone
 I went to go back my celica in the garage last night and as I walked behind the car I got a strong smell of petrol :s My assumption is the O2 has gone bad (as my fuel consumption has gone up slightly) as well as idle is rough sometimes. How can I easily (and cheaply) diagnos a faulty O2 sensor ? mines a 3sfe Thanks also no CEL has come up ... Yet lol

Code 21 is primary O2 sensor, so it's the one in the exhaust manifold or right below it. Which would explain the reduced economy.
