1st...Well My light came on with a Historic Code:

P0140
O2 Sensor Circ.,Bank1-Sensor2 No Activity Detected

The question is Where is Bank 1, Sensor 2?? And is the Not Activity Detected Means that it needs replaced??or is it just a Glitch??

2nd...What brand do u guys recommend for Spark Plugs??



thanx guys

NGK is OEM replacement at about $6-7 USD. I just replaced mine with BOSCH Platnium+ 4's. for $6 USD each.

i replaced mine with autolite platnium no complaints ( from what ive heard the +4 may last longer but they dont do much for preformance)

bump on the 02 issue

i have a car that got that exact same code ( but its been having troubles anyway)
