As soon as outside temperature gets above 35-40 car starts fine. I'm thinking it's a mass air sensor or a fuel injection problem. please advise I'm lost.

I had the same issue with my '89 many years ago. It wouldn't start when it was very cold outside. Persistent attempts would flood the engine so badly, fuel would end up in my oil. I finally took it in. Replacing the distributor cap / coil pack (all in one these days) did the trick. It just wasn't putting out the necessary voltage on cold days. My Bonne has be great ever since. 386,000 miles and still running great. Hope this helps.
