Question about 1993 Saturn SL2
I GOT THE PROBLEM FIXED ON MY CAR!!!!
After much research on the internet, a family member found that if your coolant sensor is bad, it can prevent the other sensors from resetting. And since the coolant sensor isn't typically tested in the emissions test, it won't show up as needing to be replaced. I suppose it also won't trip your check engine light, since mine wasn't on. We pulled the sensor out and saw that one of the prongs was terribly corroded. Replaced the sensor and viola! Drove around for half a day and the car passed emissions the next!

This is what I would do. I have a 98 saturn sc2 and have been threw this ringer.
1. replace the O2 sensor
2. replace plugs with the bosch platinum 2 spark not 4, and the wires.
3. take the trotle body off - relax 4 bolts. the wost thing is you mite have to buy a new gasket if your not carefull - clean it out really good. with a lint free towel and carb cleaner.
4. buy a product called seafoam.
Go on UTube and look up seafoam its very easey to do. And typically works.
5. also replace your air filter.
6. you may need to replace the thotle body sensor
7. you may also need to replace your tempature control sensor.
Change your oil when all this is done. Take the car out on a interstate or major highway. do at least 60 miles per hour for atleast 30 minutes. Then drive directly to the inspection place. This will also increase your gas milage and performance. I do not take any responsability for anything here. I am not there to diagnose your cars but I can say this is what I would do.
If you have any questions let me know. everything I have told you to do here is very easy and can be done in no time at all. Get a friend to help
