Got a 97 Subaru legacy 2.2 auto. Lifted it 1 inch. Running 215 70r15s on it now. Much bigger then stock. Check engine light comes on 2 miles from house every time I drive it. Stalls at some stop signs and sometimes seems it goes into limp mode until I turn off and back on? Being it's an automatic would that cause the speed sensor to malfunction at low speed. Just wondering if I should go back to a smaller size tire....
