need help
You shifted from 2nd to 3rd while slowing down with the pedal all the way down and gained RPM?
Rethink your problem and explain with better detail..
"i was driving my car and while i was in 2nd my car felt like it lost power"
Could be a broken valvespring, failed O2, fouled spark plugs, dead battery, failed alternator... Needs more detail..
Are you throwing any codes? Did you notice any strange smells or sounds? Did you check your oil? Did you even look at your gauge cluster?
