Car shaking at low idle and shuts off

[NickZHP]

Starting yesterday when I would start my car it would take longer to start when I turned the ignition key and when it did start the engine would shake and the RPMs would get low then the car would shut off almost like its stalling. I can turn it on again and keep it on but the revs bounce back and forth betweem 500-1000 and the engine still shakes. Also when it drives, whatever gear I am in, when its under about 2k revs I have very little power and the acceleration is very choppy. Once i get to higher revs it acts normal and the power comes back. Could it be a bad fuel pump? No codes were thrown.

Just went to go start it again and now it won't even start.

Could be. How's the battery? Also, any smoke?

Intake boots in good shape?

Battery is fine, no smoke. I'll go check the intake boots but I am pretty sure its the fuel pump.

Check your intake as others have suggested. I had the same issue years ago. Really rough start with bad idle. Giving it a little gas solved it until the next start up. Turns out one of my injectors was leaking pretty bad. Replaced it and the problem was solved. I honestly don't know how to check for that though so maybe the other members can chime in?

Have you cleaned the idle control valve recently??

Good idea.

sounds like a vacuum leak
