94 S420 code translation help please...
 

I would really appreciate it if someone can tell me what the codes are for a 94 S420. The light lights up 9 times and then 19 times. The car is running rough. Can someone advise?
thanks

You ever get this answered?

If you are getting a code #19, you need to upgrade the chip in your computer. Contact JIMF. He will sell you a new chip which included installation instructions. Price is VERY reasonable. His email addr is jforgione@prodigy.net

As far as other codes go, here is a list from Jim's site:
