facts: 1989 Automatic 900-base with 120,000 miles
Symptoms: weird start-up when warm....specifically...when the car is driven hard and has gotten warm is shutdown and restarted there is this sound that i can only refer to as a "spark-knock"(something I guess is similiar to dieseling us old carb guys might remember hearing)...the car will start on first try tho.....tach slips down to abut 500rpm and then goes up to normal and stays steady at 900rpm.........when started cold the car starts perfectly I might add.
Relatively new additions to this area are: plugs-NGK's, FPR, fuel filter, NTC sensor...with cap-rotor and wires over a year old......
i just don't think this sound is normal and you know us Saab-o-philes.....when we hear something that doesn't sound normal it just bugs the shit out of us. And to think....I've only owned my Saab for 18 mos......I couldn't imagine a lifetime of this!
Possible suggestions anyone????
Thanks......
