I had the same problem at one time with my 95 SSEI. I bought a module for it. The one under the coil pack(*). That fixed the problem. Try getting a module, install it, then see if the problems gone.Thats the cheapest way to go. But make sure where you buy it does not have a NO RETURNS ON ELECTRICAL. This way you can return it.

Or simply trade for a day with a friend or family member. 3800'* are all over.
