So heres the problem, after my car sits all night i will go to start it up in the morning and if i dont keep giving it gas itll die off. say if i just turn the key and give no gas it just dies. also under normal driving every now and then i hear a popping sound coming from the right side in the engine bay?? my vacuum gauge reads 10-12 at idle which i know is low but i have checked all vacuum lines and as far as i can tell they are fine, where else can i check for vacuum leaks that might be related to this problem? any ideas?? thanks in advance
