I have a 91 2.4 HB. 241,000 on the clock. I am having a wierd issue with it. When the motor gets to normal operating tempature, if you cut if off it won't restart. It turns over very slowly, almost like it has a weak battey. I thought is might have been the starter, so I replaced it with no luck. I then thought timing was off, checked timing, still no luck. I have cleaned the engine grounds and it has a recent tune-up. Any ideas of what it could be? I'm lost.
