For those with a FR Wilks PP2 chip installed
Correct me if I am mistaken but iirc the o2 sensor is not needed when using this chip? I have been suffering idle hunting recently. Now for the record....no vacuum issues and the ISV is new as well as the TB gaskets.
Thanks in advance! Dal

I believe it depends on what version chip your useing, but I do believe the last version of the PP2 did not use the O2 sensor, try unpluging the sensor and see what happens

It is already, may reconnect it but then again this issue is new and ran ok before so I am leaning towards the TPS. Just trying to get some imput before I get the big hammer out.
 Thanks Dal

the PP2 chip ignores the O2 sensor.
