Check Engine Light
 

We have a 98 LC with 106k miles on it, it ran perfect until the other day when it became jerky and hesitant, then today the CEL light came on and it remains like it was, upon starting it seems fine but when in gear and not giving gas the whole car shakes but when we give it gas it seems to smooth out. Any Ideas?

Could be alot of things, best thing would be to get the code read, free at autozone, etc... Check the 100 series forums at ih8mud.com
