I replaced the upper O2 sensor a couple months ago and now the second
one is bad, my understanding is that O2 sensor 2 is the one lower
down/farther along the exhaust path.
The one I replaced a few months ago was on the front of the engine,

2000 1800cc J2 Lantra. Under load occasionally the engine feels its running
on 2 or 3 cylinders. One revs > 1500 rpm no problem. Gentle acceleration no
problem. If it were a carby I,d say the fuel pump on carby was defunct but
on fuel injection?

Anyone know how ??? I can't tell how to get it apart and don't want to break
it....Will it need re-programing after the battery is removed and replaced
??? Checked the Owners Manual with no luck....Thanks for any help....

I need to run a cleaner (atomized solution) through the vent system of a
car owned by a heavy smoker. Already tried cleaning the cloth in the
vehicle, but the air system needs cleaning.
Anyone know where the air-intake (fresh and inside) are located?

My 06 V6 Sonata sputtered upon fire-up this morning.  I turned off the
ignition, turned off the defrost / blower and the radio.  Tried it
again, and it did it again...until I tapped the accelerator, which got
the engine humming in no time.

Anybody have this problem? 2003 Hyundai Santa Fe 2.7 V6. Is their a reset
that can be reset or do I have to take to a Dealer?
