06SubLegTx Posted November 26, 2017 Share Posted November 26, 2017 Hello, Here I go: 2006 Legacy 2.5I Automatic When I am drive @ 65-75 MPH with Cruise Control on, and the car is between a hill and flat area, I can feel the car "accelerate" then "decelerating " more that I think it is suppose to. I run 93 octane fuel. Injectors were professionally cleaned and tested. New Plugs, Ignition Coil(Subaru), Ignition Wires (Subaru), Timing Belt New (Subaru) all new components (Subaru) The engine runs smooth. I just notice this when cruise is on going up a hill. Thoughts?

Infosecdad Posted November 26, 2017 Share Posted November 26, 2017 How long since you had front wheel bearings replaced? If they have been replaced, were they replaced with OEM bearings or aftermarket? Link to comment Share on other sites More sharing options...
06SubLegTx Posted November 26, 2017 Author Share Posted November 26, 2017 The driver side I think is NOT Subaru, and I get a code (No Light) from ABS System. I did put a NEW Subaru Sensor in, but still get a code. Link to comment Share on other sites More sharing options...
Infosecdad Posted November 26, 2017 Share Posted November 26, 2017 It's pretty well documented that non-Subaru wheel bearings can mess with the cruise control. The previous owner has both front bearings replaced with non-subaru bearings and my cruise control would surge something fierce and just quit working. Once I replaced the with OEM bearings all was well with the cruise control. Wonder if your tone wheel is messed up or if it's a different one than the one you replaced.
