Hey guys I have a Japanese alto 2009 model G2 variant 660cc (HA24S) it has K6A engine and 180K mileage , I am facing two problems one is acceleration issue like it has become sluggish / dead if its at 20 or 40 it stays at it until I press the pedal hard sometimes once it goes to high speed the race feels normal , also it and also its consuming too much fuel , fuel that use to last 3 weeks easily isn't even lasting 2 days now until it goes into reserve , I don't even drive the car that much , things I've tried so far got its catalytic converter and throttle body cleaned , transmission fluid changed and spark plugs changed , air filter changed and engine oil changed but it made no difference
Need suggestions on what should I get checked and also suggest me a good place in Islamabad to get it done from
