Howdy,

So frequently the posts about 123s on the forum are from diesel owners, it has made me curious to know what differences there are between them and my 123 gasser. For instance, I've been researching vacuum problems and am wondering if my car can also take performance hits if there are vacuum leaks. Any information about the differences between the diesels and gassers would be very interesting. Thanks
