My car got the hicups

[Renard_noir]

So, today I try to drive and the car is acting up
1. When I started it, it didn't want to stay on I had to give it gas so it could stay running
2. The car is having some sort of issue.
When I shift 1-> 2 I get to 2.5k rmp it's starts jerking and loses power as if I pressed the brakes.. I shitft to next gear
same thing. Go back to 1st everything look normal until I shift again.
I have a 1995 240sx se. Ka24.
Somehelp will be greatly apreciated.

Thank you for the tip. I'll get tht tested and see if that's the issue.

almost sounds like you have a vacuum leak listen and look for loose or broken hoses on the intake.
