Hello my name is ***** ***** thank you for your question.

The most common thing that can cause your issue is actually the MAF sensor. 90% of the time the MAF ( Mass Air Flow ) sensor heated element which meters the air so the computer can add the proper fuel mixture has fallen out of spec. Not enough to cause a Service Engine Soon light but enough to cause the Air and fuel Mixture to be so off it can cause No Start, Stalling, poor acceleration, won't rev over a certain Rpm, and running issues. I would have the Air and Fuel mixture readings checked to verify. Checking the voltage will not show the fault, the air and fuel mixture will. If found to be bad, do not replace with a After Market one. After market MAF sensors never seem to work properly. There heated element doesn't work right which can cause 02 sensors to flat line and have you chasing you tail trying to figure out what is wrong. So the only way to correct this issue if you do have a bad MAF sensor is to replace it with a OEM.
