what do you guys think? I am a new, so have no idea. need help, hurry up!!!!

 

Telling us to hurry up, being so vague, and having this many spelling errors isn't going to get you very far here. Just a heads up.

For starters:
- Where are you located? (Country?)
- Did you pull the CELs?
- Is the car modded?

 

Hurry up and replace your IM.

Both the purge valve and intake manifold gasket as well as some manifold replacement seems to be common on here. However I would be a little ticked at the shop for not fixing it the first time. Could be a fluke though both failing similar times

 

So you did the intake gaskets? The pvc valve on the back can leak, the rubber inside can tear. Some have experienced a crack on the manifold, try locate it and seal it.

 

take a look around the intake for any cracks ..if it's just the seal you can just replace that but if it's cracked you'll need a new intake, yeah you can seal it but the crack just gets bigger..at least that's what happen twice in my case
