It's difficult to find good (deep) discriptions of Trionic, do you have one ? > > /ROM You are actually right, Saab's Trionic does not appear to have an air mass meter. It is quite complicated: For the 2.0 engines, Trionic and balancer shafts was introduced from the 1994 model year. The 2.3's had Trionic since 1993 MY. My 9000 is a late 1993 model with Bosch LH-jetronic, but it has DI cassette which I thought belonged to the Trionic models? I have the usual Haynes manual, but always wanted something better. Please reply/write in the ng as I can't reply to your email address for some reason that I don't understand; the mailer keeps rejecting it. Johannes
