I have a 2003 F250 6.0 that is currently having a couple of issues. First being that it idles around 1,000 rpm when in park all the time. Second being when in drive and stopped it idles all over the place. Tends to surge forward also. The idling issue is erratic. It tends to jump all over the place and almost sounds like it's going to stall. I pulled out the EGR valve and it was dirty. Cleaned and installed with no change. Any suggestions? Thanks in advance.
Thanks. I scanned and got insufficent exhaust gas flow. That's when I cleaned the EGR valve with no change. I almost forgot to mention that I'm having issues with the tranny. lol. It shift hard when down shifting from 2nd to first when I'm coming to a stop. The high idling went away after the first EGR valve cleaning but after the 4th it just doesn't make a difference anymor. I think it might be time to buy a new valve. Would that also cause the idle to fluctuate irradically also?
Thanks guys. So it is possible for the ICP sensor to cause this without throwing a code? I started tearing into it and this is a beotch. Getting ready to put the new one in. Is it possible to just rig your current EGR valve as a delete but leave the cooler in? What would be the pros and cons to this?
