I've posted about this before, but the problem is getting really bad now, cant even rive 5kms without it going into harsh limp mode and blowing thick white smoke, it sounds weird when its running too, and with the hood open you can hear air being sucked hard thru the intake at idle. sometimes when it tweaks it will blow lots of black if you try give it gas to go, It has NO power when this happens, people say EGR valve, I dunno no CEL or anything, anymore thoughts? thanks in advance, might be taking it to the dealer in a few days
Not sure about the thick white smoke or anything else but when my EGR valve was clogged, and I mean one SOLID brick of soot/coke. My truck would occasionally smoke off the line, or when I would roll back into the throttle to bring it back up to about 2k rpms and have zero power. Its really easy to clean out, so I would start there if ya can. Took me about 45 minutes and it was my first time and the thing was clogged solid. 2 small bolts and then just gotta carefully pry it out. I had to clean/vacume out the extra solids in the intake as well but still didn't take all that long.
Here is a write up on the EGR servicing, http://www.forddoctorsdts.com/articles/article-06-12.php I also had no CEL with these problems, oh and compared to the pictures from that link, I actually had to do some scrubbing before I even found the top opening in the valve, thats how bad mine was :doh:
used my buddies bullydog to se if it threw any codes, not a single DTC. Apparently they are taking it to the dealership tomorrow....im worried for them
took it to the dealer, it was the EGR, you guys are so smart! it was under warrenty so no big deal. thanks guys!
