Po13C every time I let off the gas pedal between 70mph dropping back down to 60mph I own a 2008 Grand Cherokee Overland 5.7 hemi. SUPER annoying!
Tried replacing all o2 sensors and replacing EGR Valve. Engine light comes back on with P013C code. Jeep Dealership says they need to replace Catalytic Converter at a cost of over $2000.00. Not covered under 2008 Lifetime Powertrain Warranty. Been driving car this way for about 2 years.
P013C is what my check engine light code reads. It is the PCM. I need an updated software. I believe it is a recall for keeps for this problem.
