    Detroit 60 series 14L sputtering in high gears and throws out puff of black smoke

    What will cause 2005 freightliner with detroit 14L 60 series egr motor to sputter under a load and throw out black smoke when going thru gears on high side? I have changed the EGR valve and mechanic says VPOD and turbo is good according to diagnostic but actuator valve is out of specs according to detroit specifications. Has any experienced this problem or knows what the problem may be?

    My 2007 Century did that and it was the EGR valve getting stuck. I had it replaced and all the coughing, black smoke, and loss of power went away.

    Since we are talking about series 60 engines I have a check engine light that goes on a couple of times a day. It goes on when my temp gauge starts jumping around for no reason and sometimes this triggers the cooling fan to come on even when my engine is running cool. The mechanic at the TA told me that I probably have some dirt inside my temp sensor or a frayed wire.

    Where is the temp sensor? Someone told me its behind the starter but I'm not sure what it looks like. Also how do I clean it?

    I changed EGR valve last week and it's still doing it. Hearing now it could be VPOD or turbo.

    You can change everything in the EGR system and still be stuck with this issue and a lighter wallet. Best thing I ever did was do a complete EGR delete on our 05 Detroit. Runs 1 Million times better now and I actually enjoy driving it. Our truck was so bad we couldn't even drive it anymore because it would cough so bad and buck you around. Cost a lot less to delete it then it would have been to replace the POS parts and end up with the same problem still or later down the road.
