Is your CEL on? If so, pull codes.
:thumbs up

Also check the spark plugs, wires, cap and rotor, as well as the ignition timing.

If you believe the primary O2 sensor is at fault, then unplug it to see whether the problem goes away.

car hesitating when taking off

ok,recently i have noticed my car when i take off it shakes a bit, but you can notice it, and allso i have noticed the hp loss and mgp loss. but i am pretty sure that it could be the o2 sensor. Front (upstream) oxygen sensor. im pretty sure thats what it is.

which would be the second o2 sensor you see in the picture

Only one thread per topic please. Two threads merged.

Rear = secondary O2 sensor.
