Hello and welcome. My name is ***** ***** you for visiting the site.
Let me just say 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.
P1391-INTERMITTENT LOSS OF CMP OR CKP
Most times it is the CMP sensor when that code sets. However there is a test that can be done with a scan tool and lab scope to be sure.
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 test and 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,
Please don’t forget to rate the answer in a positive way, . EVEN IF YOU HAVE A SUBSCRIPTION ****THAT IS THE ONLY WAY I GET PAID ****
