Default check engine code.

i got a check engine code for p0133 and a pending p0138

im trying to get rid of this crap... i payed someone 200 bucks to put o2 similators in and they r not fixing the problem. i even replaced 2 o2 sensors. i got long tubes in the car also.... anybody know what i should do? the guy was saying something about a high voltage on my o2 sensors or something also....

Get a tuner and turn them off.

Default RE: check engine code.

That is your front sensors. no hand held tuner will fix it. You have to take it to a tuner and have them do it. With longtubes it takes to long for the o2 sensors to heat up which is what is throwing the code. It is not a big problem but if you don't like looking at the light then take it to a tuner.
