Salam guys!
I bought passo 2014 last year and I was getting aroubd 16.5 avg last year. So after coming back to Pakistan this year it was 11.5 so I decided to go to its tunning and mostly the clean catalytic convertor ans the guy did the same thing which I saw in some videos that he opened it up and put sweep in it and then all the carbon came out. Afterwards it was giving 9.5 avg so I went to the person again and he said that they will reset something from comp but got suggestion from another mechanic to just remove the battery cables and put it back for reset. After that I havent drove much but I saw that the avg went up to 10+.
Anyone give some input in my case that its normal to reset or do somethings after catalytic cleaning?
Thanks for your input.
