Hey guys.
Car runs like poo from 1-2k rpm then runs decent. Throws Code p0134 for Heated oxygen sensor front circuit no activity detected even after we put a new denso o2 in. Clear the code and it comes back within roughly 5 miles of driving. Sometimes within 5 min of just idling.
What would cause it to do this?
Thanks

Possibly a silly suggestion, but you disconnected the battery for a bit correct after the new o2 sensor install?

Battery got disconected for a few minutes.

Was the sensor a splice in, or plug in?

Plug in.

my car throws the same code, but hasn't affected its driveability. At this point I think the connection from the plug to the ecu is damaged and needs to be rewired.

Would an exhaust leak cause this?

yes it indeed can, any exhaust leak before the 1st sensor can throw a code.

did you find your problem?

Nope. Starting to think its tune related.

Got a leaner base map from my tuner. Car runs way better but same code comes back on working 5 min of driving the car. Bought a brand new denso front o2 sensor aswell.
Any one got any ideas where to look?

I got this code after following directions on here for disabling the rear o2 sensor, and it ran poorly at low rpm. I just reversed what I did and deal with the rear o2 cel so it at least runs right.

Also, why is your tuner giving you base maps? Shouldn't he be tuning it?
