thanks for the link that should be what i need.
waiting for the stealership to finish working on it. They said they replaced two up stream sensors for p0031 and p0051 now i've got p0135 which is a heater in 1/1 they are trying to say I will have to pay for it . but as far as I can tell a heater is the oxygen sensor and the installed a bad sensor. seing that 1/1 is upstream am I right?? It's under warranty but there is a hundred dollar dedctuable and the new o2's only have 50 miles on them think theyre trying to rob me as usual!!
