Hi RICHARD MAYO, Welcome to 2carpros and TY for the donation this is what keeps us going

Do you have a check engine light On and when was the last tune-up?

Check and test the EGR valve, throttle position sensor, mass airflow meter and also for vacuum leaks to include a fuel pressure check-

I replaced mass air flow meter yesterday and it seems to be running okay at this time. When the problem orignally occured it was extremely cold. The temperature is a lot warmer now. I wonder if the temperature could effect this problem
