Re: What did you do to your WK today?
Rebuilt REN MyGig head unit installed (warranty - 4th one).
Tightened the bolts between the exhaust manifold outlet and Y-pipe inlet. [Trying to eliminate minor exhaust leaks that cause O2 sensor slow response DTC's (P0133 & P0153) at cold start if I idle over 30 sec.]
The '08's 5.7L HEMI's have no gasket at this joint.....just metal-to-metal ball & socket. I this doesn't work, I'll start looking for a more positive sealing method (i.e., custom high temp gasket).
Have to give it a week or so until the LTFT adaptives return to an equilibrium value after the battery disconnect.
'08 WK Limited, 5.7L HEMI, Quadra-Trac II, Bright Silver Metallic, Class IV Hitch, Michelin LTX M/S tires, Billet Technology oil catch can, Fumoto oil drain valve.
