Had the XJ inspected a few weeks back and I passed the sniffer and everything else except the exhaust manifold had a crack. I had that welded, and re-installed it with a new gasket. Now the manifold passes but they said i dont pass the sniffer now. Last time i took it in on a warmed-up engine. This time i left it overnight for them to do when they got to it. Does that make all the difference? Also, in re-installing the manifold i routed the wire for the knock sensor wrong and it lays against the intake manifold now. Will the comp pick up vibrations from the wire being like that and then decide it's knocking thus making the mixture richer?
