My 1990 L98 is having a problem with the CCM not being able to communicate with the ECM. Both the ECM and CCM check out ok. It is only a intermitent problem the maual says to check the data wire specificaly. It sounds like it happened a few times to others. Anyone else have this problem. The manual point towards a short but where should I look first I have looked at most of the wiring with no luck.

Thank's

What nobody here has had this problem? It has been ok the last 2 days but I am sure it will return.
 
Follow the Manual for that one. Intermittents are a PAIN to find the source.
 
Oh yea of course it returned. It acts like a bad connection or a short can not seem to find it anybody else see this happen.
