Suzuki Mehran Bad Fuel Economy and Vibration Issues

Hello!

I recently bought a Suzuki Mehran 2017 model with 62,000 km on it. Its been running fine, but I recently noticed its only giving me 14 km/l on the motorway trip from Gujrat to Lahore.

I had an ECU scan done, and it showed no issues except for a broken CO2 sensor. The fuel injection pulse width was 3.7 msec at 90°C. I replaced the CO2 sensor and put in new NGK Iridium spark plugs.

Now, Im feeling some vibrations, and the idle RPM is 870. Any suggestions on whats causing these issues and how to fix them would be greatly appreciated. Thanks!

When looking into this, there are two key factors to keep in mind. Firstly, you should examine the air intake and check if there are any obstructions. Secondly, and perhaps most importantly, you need to cross-reference the LTFT graph with the RPM data.
