Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
The problem you are describing can be cause by either a failing MAF (mass air flow) sensor and or even a dirty one. I would start first with taking some MAF cleaner and giving the MAF a good cleaning , when doing so be sure to disconnect the negative battery cable to clear the PCM (computer) memory. Give this a try and post back if you still need more help and we can work from there.
