well i finally got it checked out and they told me that my "downstream" oxygen senor and fuel injection is bad and they wanted about 150 to fix the problem. well i left thinking 150 maybe a lil too much. well its been like 4 days since than and now the check engine light is off. Does this mean that the o2 sensor is randomly working fine then doesnt work?

the code is:
P0141
O2 Senor Heater
Circuit Malfunction
(Bank 1 Sensor 2)

now the people who pulled this code at autozone told me that replacing the oxygen sensor my not fix the problem. They said the code tells where the problem area is, it does not pin point the problem. What should i do? go buy oxygen sensor and c what happens or pay 100+ for diagnostic to pinpoint problem?

It's always best to diganose a problem to find the defective componant. An o2 heater is an easy check. It should measure about 10-40 ohms across the 2 black wires. Failed o2 heaters are a fairly common problem.
