Finaly got around to installing the new O2 sensor. Car was runnin rough do to the sensor going completely out.

The sensor i used is a bosch universal. All the wires are color matched as listed on the paper. But for some reason i still have a slightly rough idle. its not as bad as it once was but still there. car dose drive alot better and alot smoother threw the rpms.

I have a 2g gs-t stock 4g, stock smic, with injen IC piping and filter. new NGK plugs and wires, along with new coils.

Any ideas? car is auto

or should i drive the car for a while and see if a new tank of gas will burn some crap out. I will be doing an induction service later today.

 

recirculated??

 

By rough idle what do you mean? Idling high, low, or jumping?

 

or slowly drops like the car is gonna shut off but then after a coup[le seconds it idles fine...its the bov

 

What he said is very right.

 

Agreed, maybe try some injector cleaner too..

 

its a lil jumpy. will idle high sometimes then low.

bounces between 1000 and 200 20% of the time. otherwise its at 700. yes its rec with a greddy bov.

When the A/C is on on first start up car wants to stall till the temp builds up a bit also.

 

TPS sensor??
