Sounds like you have gotten hold of some bad gas maybe water in gas. Put in treatment for water in gas or a octane booster.

When was the last time you had the fuel filter changed ?

Last April,I have a new one unopened in my car.Do you think it may be the mass airflow or idling need adjusting. I will have fuel filter changed this weekend.

Definitely would not hurt to clean throttle body and mass air flow sensor.

Hey toolgirl what type of gas do you use in your vehicle if it is the low grade try some middle grade or high test gas that will make a difference also. You do not have to use it all the time but it helps to use it occasionally.

I will get a higher grade of gas tomorrow. Thanks

I'm sure there are some trouble codes on your car's computer. Wouldn't hurt to find out what they are before spending money on random parts and hoping for the best.
