    I have a 2003 Tacoma 2.7l 4x4 and I have noticed it idling at about 2000 rpm sometimes. When I am offroading the truck runs and idles fine until I go and rev it up to get through some mud. I always fether the gas in the mud and don't just hold it right on the red line but it aways idles high after I do this. Sometimes it will drop back down to 1000 rpm and jump back and forth between 1000 and 2000.

    Any help would be much appreciated!

    I could not find any cracks and the motor mounts are all good. I did, however, find a code for EGR insufficient flow. I cleaned the EGR valve about 2 months ago as well as the EGR tube but the code still remains. Do you think this could be related?
