Red face Help engine "shaking" during startup ( put back my stock intake nd it happened)...

I don't really know how to explain it other than it feels like when I first start up the car it feels as if the engine is shaking or so for 3 seconds where I can feel it when sitting down. It feels like it's moving left to right for a few seconds and just stops. I recently put back my stock intake and it started happening. Anybody know what could be wrong?
Help help plzzzz

Not sure, but have you tried making sure you installed everything correctly and that there are no air leaks?

I was going to say that it might be an air leak after the MAF. Any unmetered air will throw the fuel calculation off and cause that issue. Even if you're sure you sealed everything up, I would go check again.

If that's not the case, you could try disconnecting the battery for several minutes to try to reset the car's parameters.
