SOURCE: I need an engine diagram for a 1995 saab 900 se V6
A SAAB dealer should be able to print one out for you. BTW that engine is practically identical to the V6 used in a caddy Catera, and Saturn Ion. Those diagrams would be the same, so you might want to search that also.
SOURCE: rough idle on 1990 saab 900 convertible, 16V
Because the car has adaptive technology, it may take a while to reset and adjust to the new, cleaner and better conditions than those to which it had previously adapted.
Did you change the cap and rotor? if the plugs needed replacement, likely they do too
Possible other causes include:
loose or corroded connections to any electrical component you disturbed (make a checklist and tick them all off as you check them);
mis-reinstallation of any F.I. part disturbed(checklist again)
obstructed water flow through the AIC valve;
improper voltage output from the AIC valve (for LH 2.4 systems, should output 8 volt at idle, dropping as load increases; for LH 2.4.2 system output 7 volt at idle etc; testing between terminals)33 and 17 at disconnected LH connector;
possible problem with MAF.
Hope this helps

SOURCE: need radio code for 1995 saab 900 se
sorry but there is nowhere/body to find out what the code is...the first owner could have written it in the service book but "is that too much to ask...."you will either have to replace radio or an i.c.e.dealer may bypass the code for you .
