Hello all, I need help here and its serious. I changed my oxygen sensor and drove like 30 miles. I went to emissions. My car still fucking cams. I don't know why it does this. It sucks a ton of air in, rpm go really low. No misfire code. The codes that came up are these, 0132,0140,0172. Could it be my maf? I need advice on what to do, if I don't pass Monday they will suspend my plates. The caming is completely random, sometimes it doesn't do it at all. It gets to the point where if you nail it, at full throttle you won't even move, all it does is bog. What can I do??
