Hi guys. I recently replaced my NOx and all is well - engine running fine, no misfires and no codes. The exhaust seems to be more sooty than normal though. I recently put new plugs in and the index 11 injectors all seem ok as none of the plugs were wet or overly black. All seemed similar. Car does seem a bit less powerful these days but its still pretty quick so maybe im just more used to it (had it 5 years).
Any ideas? could it be the coilpacks or maybe the inlets - is on 70k.
or maybe im just over reacting. Its hard to quantify but it seems more soot than it used to.
