It's .040
Defective spark plug or plug wire, burnt valve, blown head gasket, fuel injector problem, or broken piston ring.
possible misfires caused by spark plug/coil wires
Just did mine today, they should be gapped at .040".
there are many variations depending on preference. .040 (stock) is fine
One kind of spark plugs that is recommended for a 1999 Saturn SL2 manual with a 1.9 twin cam engine are ones made by Bosch. Another good brand would be ones made by NGK.
The Saturn SL2 was produced from the years 1990 to 2002 in the United States. The best way to tell if the fusible link in a 1999 Saturn SL2 is fried is that there will be no 12v.
Spark plugs, spark plug wires, throttle body cleaning / decarbonization and fuel filter would be a complete tune up on your car.
