Re: PO455 DCP valve
Regarding the O2 sensors, jeeps like the original Denso´s the most. Eventhough Bosch is a very good brand, they heat up too slow in many cases (for our jeeps) and you will end up with O2 heater codes.
And regarding the TPS, i think you didn´t order it yet, isn´t it? Rockauto doesn´t have the OEM TPS, so you better buy OEM from some place.
Sorry i didn´t tell you before, but when you google " Rockauto discount code" you will get some 5% discount codes to use when buying.
