Hello Dear.
I have suzuki alto jdm 2010 with auto tranny.
I am getting a 20km/l0 on highways
But
Very liw 13-14km/l in local.
Both with AC ON.
Moreover car pick up is also not as responsive as it should be.
The same case is with me. I get my car scanned. And it shows.
DTC Code P0420 (Catytic Converter Efficiency Below Threshold Level; Bank 1)
What should i do.
Cleaning CAT will work?
Cleaning it with Acid? Harpic? Water Presure?
And more, you said ypu changed the clutch plates etc. Is it necessary for good pick uo and to improve fuel efficiency.
