1998 Civic with auto transmission started over-revving on up shifts and sometimes shifting up with a hard clunk. This happens once the engine is warm. At start up, within the first minute, regardless of whether the engine is warm or cold, the engine usually bogs (refuses to accelerate) two or three times before running fine. Throwing error codes of PO170 and PO171. I cleaned the throttle body, IACV, and all other attached components and that took care of some erratic idle issues but not the bogging and hard up shifting. Now it is idling high in park and neutral. The exhaust smells odd but not like burning oil or antifreeze. Anybody got any ideas or solutions?
