the car suddenly changes fuel consumption and emits black smoke as if no total combustion loses power. It has a high rev when idling.

Hi Blessing Nyasha Chikowore,

I am sending you a couple of links from our site; the first is an easy step by step guide on how to detect and fix an automotive engine vacuum leak, this information pertains to most vehicles. The second one is to an article that features written step by step instructions and pictures explaining how to do the scan yourself; also I have included a link to our YouTube channel with a how to video on code scanning.

Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com.

Once you have the codes please get back to us so that we can further assist you.
