My 97 Impreza 2.2L auto feels weak with some hesitation around 2000-3000rpms with approximately half throttle applied. Doesn't hesitate with very light or heavy throttle (e.g. during tranny kickdowns). Occassionally the idle will hunt between 500-800rpms.
No CELs but could the MAF or some engine sensor becoming defective produce poor performance but not throw a CEL?
