U1120 DODGE - $07E8

Question

Hi I get U1120 ($07E8 and $07E8N) error codes for my 2006 Dodge Durango.

Sometime the yellow engine oil pressure light indicator comes on but then disappears or I restart vehicle and disappears on startup.

I often get my RPM revs irratic ie high and low while I am stopped as if it is about to stall. Upon restarting my vehicle it goes away but it returns from time to time or shortly thereafter.
Any suggestions.
Thanks. Mike

U 1120 Lost wheel distance message

This is for ABS, This will not cause erratic idle,What can cause this idle problem are a slightly open EGR, A carbon up IAC (idle air control) Do a throttle body cleaning and clean the IAC entrance, See if that helps and solves this problem
