Hello to all, I'm new to the site so please forgive any rookie mistakes I may make. My '93 L.C.'s engine light has been acting up a bit and while I'm well aware of the fact that it could be one or more of a number of reasons. in this particular case, it seems to come on upon deceleration and turn off when I accelerate. If anyone out there can make sense of this for a potential cause, I would really appreciate it......Thanks
