Thanks - Smoking
Thanks for your help.....here is an update.
So far I've verified it is not burning crankcase oil and the air filter wasn't plugged.
I'll next get the codes checked and have it checked for leaks.
I'm wondering if it couldn't be my driving style as I never really go fast.....or far (a tank of diesel usually gets us through the month). There is very little traffic where I live and I seldom get above 2000 RPM and in fact probably average 1400 RPM. The only time it really smokes is when I have to speed up suddenly to prevent getting run over.....normal driving it doesn't smoke.
