My car keeps stalling. It started to do it randomly a few weeks ago. It would shake a little and die when i would put it into first gear and try to drive off. When it starts to shake, i hit the gas but it is unresponsive. I have no check engine light. I have put in a new battery, idle sensor, air filter and spark plugs. I also cleaned the carbon buildup. It is also starting to do it while driving. My car starts to slow down and when i hit the gas pedal nothing happens. I used to restart my car and it would be ok but as soon as i turn it off for more than 10 minutes, it would do the same thing. Now it is doing it more often even after i restart it.
When the mechanics did a scan test, nothing comes up so i am assuming it is a non-mechanical problem. It is a 2002 civic ex with 114, 000 km's on it. I run synthetic oil and change it every 6 months or 10,000 km's, w.e comes first.

Please help!

 

Is it a manual? Because if it is, it kinda sounds like when you don't hold the clutch long enough and the car shakes and stalls. Perhaps your clutch is going bad?
