My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received 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.

If you have not had the engine checked over for any vacuum leaks this needs done.If any vacuum leaks are found they will need repaired to correct this fault here.In some cases this will take a smoke machine to inject smoke into the intake to locate any hard to see leaks like the intake gaskets leaking needing replaced.If this was already done and found o.k. let me know.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete
