91 ex Eratic guage cluster.
 

I have a 91 EX with abou 180,000 on it. Over the last week my guage cluster started to freak out. The S light blinks and the speedo will just quite and then come back on. I can turn the car off and back on and its fine. Tonight the check engine light was added to the light show and now the only functioning guage is my RPM's... The car is still running like a top so I am puzzled about this... I thought that maybe my tranny was low on fluid but it's perfect! PLEASE HELP ME!!!
