Problem with my Z posted by Wally_562 on October 26, 2012 at 02:16 PM

if this were happening on my Z I would test the fuel pressure, maybe a bad regulator, pump, or filter. Then maybe run fuel injector cleaner for a whole tank. If everything on the fuel system checked out then I would do a boost leak test. If that checked out ok I would be investigating my wiring harness for corroded points.
Remember: the more details you give us and the more tests you do= the better we can help you
