[DeTomaso] Problems with engine shutting down

[Larry Weston]

...still has all the smog stuff...
 
Vacuum leak? Check the various vacuum lines at the nipples, see if they are hardened or split. Just had a HD Sportster in my shop, stalling and poor idle due to one hardened line and split line. Looked ok, until I pulled it off, the splits were in the lining of the hose.

   ...still has all the smog stuff...

   Vacuum leak? Check the various vacuum lines at the nipples, see if they
   are hardened or split. Just had a HD Sportster in my shop, stalling and
   poor idle due to one hardened line and split line. Looked ok, until I
   pulled it off, the splits were in the lining of the hose.
