Re: PO455 DCP valve
Regarding the O2 sensors, jeeps like the original Densoīs 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 didnīt order it yet, isnīt it? Rockauto doesnīt have the OEM TPS, so you better buy OEM from some place.
Sorry i didnīt tell you before, but when you google " Rockauto discount code" you will get some 5% discount codes to use when buying.
