I know was working good and still have the same problem guy help please guy I need this car running sorry for my English if something is spelling wrong guys

 

Can someone give me and idea where I can look for the problem

 

Spray around all the vacuum lines with brake cleaner or starter fluid and look for the leak. if there is a leak you will hear the engine rpm change.

 

Than ok u 99teggsr the intake gasket was leaking is fix already

 

Is your MAP sensor hooked up ? Any Checl engine light ?

 

Yes my map sensor is hookeup and no I don't have the check engine light on so I guess I have no code
