They have crank sensors just not a cam sensors. I had a similar
situation with a 3.8 and I reached down and could move the sensor
around, it had worked loose and was rubbing on
the...whatchamacallit...steel ring with what is often described as
shutters. Anyhow I would suspect that unless it said "cam". In that case
it would probably be the ignition module or something that has to do
with "compression sense". Btw dont play with your plug gaps especially
if they're platinum and be sure to check the resistance of your spark
plug wires.

Check the routing. OBDII saturns are picky about plug wire routing
because they need it to be the right way to sense something weird.

After that, suspect the crank sensor, and if that's not it, ignition
module.

I've had the exact same problem with my 96 SL1 for the last 4 years.
(Since I bought it, used)

After replacing plugs, plug wires, O2 sensors etc to try and fix the
problem, I stumbled across this.

I did as they recommended (Buy new plugs and gap them at 0.04 instead of
0.06 and VOILA! The problem is long gone.

The silliest thing imaginable, but it works.

First I've ever seen this. The TSB 96-T-25 does show up on Alldata.
Thanks for the info.

The error he is getting that he says the car doesn't have is likely a cam
sensor error, which relies on the routing of the plug wires. The car doesn't in
fact have a cam sensor per se, but with wires 1 and 4 routed next to each other
near the coil it senses which cylinder is on the compression stroke; that
acting as a cam sensor.
