Hello. I have a 2003 kia spectra with stick shift that stalls. It never stalls when driving in 5th gear, (the highest gear I have for going 55 miles or higher) however all other gears it will stall out of no where -- accellerating, slowing down, etc. It stalls quietly too and the check engine light, battery, brakes, and oil light come on, on the dashboard. I already had my 60,000 mile service done, timing belt, manual transmission flush, spark plugs, brakes, etc replaced. Also recently had a bad mass air flow sensor replaced too. Any ideas?
