Bhaio i have recently got corolla 2015 gli. Masla yeh Hai k aksar shoot bht slow hai ya foran nai uthti gadi . Aksar office k ramp pe oper chartay hoey jab 2nd gear me uthao to race mar jati hai gadi wapisi nechay ajati hai or seedhay road pe sai chalti hai speed me but acceleration bht mari hui hai. 55000 km chali hui hai gadi or plugs nai change kiye abhi tak. Last week c petrol avg b 11 dikha rahi hai jab k me sirf late night chalata hu gadi open roads hoti hai pehlay 13 14 km dikhati thi. Please suggest kya masla ho sakta hai?

Clogged catalytic converter is the probable cause.

55000km pe fuel pump ka masla nahi ata....they are long life
.
U say plugs are not changed since start? Now at 55k har haal mein chnge krne hongay
.
Plus always remember jb charhan par ho to humesha 1st gear pick karein....not 2nd gear

Still....even if in motion speed will decrease in 2nd....i wud say to stop at start, then go up all the way in 1st gear only

also check the fuel filter both the inline one and the fuel filter in the fuel tank.

Dear all the culprits were bad plugs. Now i have installed new plugs and working fine now. The pickup is good and no starting trouble, new denso plug cost 200 rs each

They are simple copper plugs....,install Platinum ones and use them till 70000 km .....for copper ones ...they last 20000-30000 km

o bhai fuel pump change na karo... nai museebat me par jao ge. nai chinese and japnese fuel pumps kuch arse baad high speed ya rpm pe sar jate h. plz use the original one. gari ka catalytic converter saaf karo ya remove karo. otherwise change the fuel assembly filter not the fuel pump.
