The car slightly jumps parked just idling then when taking off like it does not want to go and it does, even my check engine light starts blinking for like 30 seconds, so usually for none of these to happen I got to be very gentle when accelerating. The car does this at any speed down the road if I am not gently pressing the gas pedal.

Hi,

If the check engine light flashes, that indicates the engine is misfiring at that time.

Before we get started, it is important to scan the computer for diagnostic trouble codes. By doing this, we will know which cylinder, or cylinders are misfiring and then we can focus on them.

Most parts stores will scan the computer for codes free of charge. Have that done and let me know the results. If there isn't a place to take it, here is a link that explains how to scan the entire system. Hopefully, you have access to a scanner.

If you are unable to get this done, let me know when the vehicle received its last tune-up, has anything been checked as far as the fuel pressure, engine vacuum leaks, and so on?

Let me know.
