When I got back in town, my mechanic said he knows what the problem is and I watched him tighten the battery ground cable at the engine.
My mechanic said he spoke to another mechanic friend who said he mistakenly did just the same thing. He said he must have been interupted while doing this specif work and forgot to go back to it when returning to my Minivan. He appoligised and all seems OK so far.
My mechanic is not perfect, but is always honest with me.
Thats for all your input, advis eand help.
With much appreciation.
