Hello. My name is ***** ***** you for using the site, I will be happy to assist you today.

.

Let me start by saying that any money that you paid, or if you have a subscription, that money stays in your account until the answers are rated, (positive) regardless of how fast or how long it may take to get finished. You can FOLLOW UP AT ANYTIME, even after rating.

.

There has been a factory service bulletin, (not a recall) for that type of concern. You will want to check the injector "O" rings and if they are good, (and no other vacuum leaks) check or replace the idle speed control unit.

Here is a link to what it states. You can copy and paste it into a new browser and rate the answer on this page.

If you accept my additional service request for your email address, you can give me your email in a private info box and I'll send you the instructions in a PDF file, the file is rather large.

You will just have to accept the additional service offer and ENTER your email address in the “ENTER CONTACT INFO” section so that I can see it.

I do not have access to your email address,
