Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hi, Welcome to Just Answer!
The most common issue with this model is a failing fuel pump that causes the described condition. If you have not replaced yours yet, you might as well get it over with. Also, the fuel pressure will test just fine when the vehicle is operating just fine. But If you test it when it won't accelerate, you may find it to be lower than normal. Again, this is the most common cause for these symptoms.
If a check engine light is on then it is a whole different story.
If you need further assistance let me know.
