My Astina BA 1800 (high km) was running well but suddenly developed a low rev misfire after coming off the highway. Starts fine, but when throttle applied it misfires briefly at the low revs. No misfire at higher revs while standing.
throttle plate may have buildup of dirt, clean with gum out or solvent,also check air filter and airflow at engine
