My 99 cougar will start, but shakes violently, when you put it in gear it moves then stalls out, while still shaking violently, the check engine light is steady on, have had no indications of any problems until now. The car ran perfect just the other day.Please please help

OK the first thing is when was your last tune-up?
If the check engine light is on steady, The car is trying to tell you what's wrong. Think maintenance first, get it running well enough to drive to autozone. They will check the code free!
Once you get the codes if the car runs well after a tune-up, have them shut off the light. If it comes on again let us know what you've done recently and what the codes are! Remember we are not there to diagnose, more info you can give the better!

Suggested Repair

Start with a tune-up and basic maintenance, then have the check engine codes read free at an auto parts store. If it runs well afterward, have the light cleared; if it returns, report the codes and any recent work.

A 1999 Mercury Cougar starts but shakes violently, moves briefly in gear, then stalls while still shaking. The check engine light is steady and the car had been running normally. The expert recommends maintenance and a tune-up first, then a free code scan so the stored fault can be identified.
