hi and thanks to all in advance.I have a 2004 excursion 2wd with 6.0 2003 build.The truck has only 65000 miles on it.About 2 mounths ago i had the egr delete and oil cooler changed out along with new ipr ,and i think the icp,,updated turbo drain tube, new oil supply lines under valve cover i think.they also installed a new wiring harness for the icp.This is most of what was done that i remember without digging out invoice.The truck ran fine until three days ago. Now it will bog down real bad at idle or at high speeds. It doesnt do it all the time.It doesnt totally die but when u give it gas it has no response almost.it always clears itself up and then seems to run fine.I do have a scan gauge but truck has no check engine light on or codes for scan gauge to read.PLEASE HELP THIS IS OUR FAMILY VEHICLE AND WE R SUPPOSED TO GO VISIT THE INLAWS IN 2 WEEKS. I CAN RUN THE SCAN GAUGE TO GET ANY NUMBERS U NEED I JUST DONT KNOW WHERE TO START. ALSO I HAVE NOTICED NO SMOKE WHEN THIS OCCURS.
