Question about 2000 Saturn Ls 4dr Sedan
SOURCE: saturn sl2 emissin problem
If the SES light is on, take a paper clip bend it in a u-shape and jump the scanner input positions A B. This should flash the ses in sequesces to give you the trouble code, Please see the following link. http://www.troublecodes.net/GM/ Refer to the code to see what the issue may be. SES lit means that there is a emmissions related issue. Refer to the other links for additonal information on O2 sensor resistance, and the egr valve solinoid. Check the EGR is relitive easy for operation. Remove the vaccum hose and place a hose of similar suckon the hose to pull vaccum if the diafram underneith retracts, hold the vaccum by plugging off the tube with your touge if the diafram retracts, will not hold the vaccum, it is bad. The solinoid should read 40-60 ohms if good. http://www.saturnfans.com/forums/index.php http://www.aldlcable.com/sc/pages.asp?pageid=21

Burning oil...Engine miss. lazy o2 sensor.. dirty maf sensor. check the data on a scanner and this will tell what is amiss.

possible but could be head gasket or valves , or worn rings and is by passing the pistons going straight out the end ...or maby settings are wrong ? try carb cleaner and inspect visually air-filter etc.
