  • Welcome to Motor Vehicle Maintenance & Repair! What exactly is your question? – Pᴀᴜʟsᴛᴇʀ2 Oct 15 '17 at 19:05
  • @Pᴀᴜʟsᴛᴇʀ2 The car shows check engine light when fuel tank is about to 25 pc. RPM also drops at idle position – user3102991 Oct 15 '17 at 19:08
  • Okay, I think you said most of that in the body of your question, but I'm still not getting exactly what you want answered. Have you checked the fuel pressure to ensure it's good? What is considered a "low fuel level"? What does "low fuel average" mean to you? What is low rpm considered? Low on power as compared to what? If you can help us out here with a BUNCH more details and a true question (what exactly are you trying to solve), we might be able to help. Please edit your question and throw as much information into it as you can, please. – Pᴀᴜʟsᴛᴇʀ2 Oct 15 '17 at 20:46
  • @Pᴀᴜʟsᴛᴇʀ2 Thanks for ur concern regarding to my question. By low fuel level I mean fuel level in tank. When the fuel tank level is about 30 percent check engine light comes on and on checking with obd scanner it shows system too leam p0171. – user3102991 Oct 18 '17 at 11:05
  • Low fuel average means that car consumes more fuel than it is suppose to do. And rpm are also not stable. It shows shaky behaviour when shiftung transmission – user3102991 Oct 18 '17 at 11:06
