well i want to know wheres the best place to buy my 2 oxygen sensors for my max 1995 VQ. i think just the 2 that is attached to the y pipe has to be changed.

My gas is almost good...but i think the sensor is bad...i check with the haynes manual method...check the resistence of the heaters...and it a little more that on the manual says...so it should be replaced.

Another question guys, whats the diference about the front and rear oxygen sensor...talking about the y pipes sensors...why in the manual says that the both sensors will give me differentes reads Volt.

guys my upstream sensor should read on the voltimeter 2.3 to 4.3....and it reads to 7.3 on operating condition...so it means its dead??
