Question about 1993 Saturn SL1
I have been told to try a number of things to bring the count down but nothing has seemed to work[drive x amount of miles,put in fuel injector cleaner, put premium gas instead of regular,etc. But no change) any suggestions
Take a look at the spark plugs to see if they are oil on them or carbon build up from oil... if that is true... oil rings maybe bad... an old trick that sometimes work is to raise rpm to 2500 and hold for a little bit just before they plug the sniffer in.

SOURCE: 98 Saturn SL 1 sputters
Have a scanner hooked up to your car and do a data stream to see if your knock sensor is still working. On a heavy load, if the ECM detects detenation in the engine, it will automatically want to ****** the timing to make it run better on a load.

SOURCE: car wont start
At first, I thought 'coil pack'. But you said it tried to start. So that's out. You might check that you're getting spark just to be thorough.
Did it ever start again after the stall on the interstate?
If not, I'm leaning towards the timing chain.
What happens if your timing chain broke:
Do a compression test on all cylinders. If only one or two have compression (or one or more have zero compression), I'm tipping over towards the timing chain.
Have a compression test done.
Hope this helps

I'd change fuel filter, get it low on fuel. Add a bottle of rite aid 100% rubbing alcohol. Nothing fancy. Nothing scented or colored.
Add it and fill up your tank of gas.
I've done this with old cars and trucks.
Most recent was my 77 for highboy. Emmissions guy said it's emmissions were lower then most cars he saw! Let alone and old crappy ford.
If it were my car I'd drive it hard the whole way there. This may or maynot break loose carbon buildup in your cats, which will also help. By drive hard I mean higher Rpm then usuall. Don't race it, or drive dangerous. Just trying to get *** much pressure buildup in the exhaust to knock some of that **** out of there.
( been building cars for 10 years daily. You'd be suprised what little things will do to help) goodluck to you.
