My car kept throwing the 4--3-5 code so i replaced the o2 sensor, well I bought a universal 4 wire heated o2 sensor, now i keep getting 2--1-2 code saying the sensor signal is faulty or missing, i have it wired correctly, and have checked thoroughly for vacuum leaks, anybody tried these sensors before, I mean the instuctions had specific details for my volvo, i double checked the crimps on my connections and everything, and oddly it won't throw the code at idle, only after i drive it around for a minute or ttwo, any sugestions?
