When the temperature outside is around 45 or lower when the engine is cold my truck surges for abotu 20 seconds then it evens out and runs smoothly. when I use the block heater there is no problem. Any ideas on what could be causing the surging problem. FYI, I am going to have the egr delete kit installed and a bigger oil cooler installed in a week. I have 86000 miles and it a 2003 model.
