My engine light stays on and blinks while I'm driving, especially with acceleration.

Thank you for writing in. When a check engine light turns on, you will have a "diagnostic troubleshooting code" saved in the vehicle's computer. Have the vehicle scanned for codes, which can be done at most automotive parts stores and by any mechanic. Use those codes to help dianose the issue and make the appropriate repairs. Without more information from the vehicle's computer about what issues it is detecting, there is no way of knowing what the issue could be. Good luck!
