intermittant speed sensor failure resulting in limp home mode. car bucks when you hit 3500 rpm. checked all wiring changed electrical pick up. need advise for changing to tach output for signal to computor or any alternive fix. thinking of runing new positive lead to sensor in case fault lies there. car will return to runing normal in a few miles after limp home mode. thanks for any suggestion. subaru dealer ran code right after it happens when car was stil runing and got speed sensor code.
