I recently installed a new exhaust system sans cat and am noticing some blue smoke only at idle in drive... Seems to do it as the unit is getting up to operating temp. My friends lly does the same thing.... Thoughts?
04 with 25,000 miles. only mods are magnaflow duals and k&n panel filter, no programmer of any kind. The weird thing is that it only does it at idle in drive, when you throw it into park it clears out, as well as when you step on it.
Did some more homework, it looks like this has something to do with injection timing as it is getting up to temp. Had the balance rates on the injectors check out and they were perfect . Looks like nothing to worry about.
