Ok fixed the overheating issue with a. New waterpump and low temp thermostat I replaced the aos because of the vacuum coming from the oil fill pipe everything fine except the hesitation when I step on the gas two codes illuminated the cel one o2 sensor stuck open bank two sensor second code can’t read data from powertrain control module wich explains the car staying in second gear too long I don’t see these modules for sale or is it called something else from my understanding is theees one up front and one in the trunk of the car has any experienced this should I start by changing the sensor see what happens wich sent cheap 200 oem not sure if the module is faulty or could the vacuum leak set both of these off ?? Lil help I would greatly appreciate thanks
