Need Help - Toyota PASSO

[muhammadumar10]

I have Passo 2007, its acceleration is not constant during run, sometimes very gud and sometimes very lazy, chalti chalti khud hi tez ho jati ha, No warning indication, kindly suggest any possible solution? Is some sensor is malfunctioning??

i have noticed these older passo's are usually engine swapped now
and with messy wiring in most cases
if recently purchased go to efi electrician to get check wiring and if cel is connected and functional or not

[muhammadumar10]

Engine is not swapped, on scanning there is no error code found....

throttle body and sensors around it full servicing (TPS-AFM)

[mgalaxy3]

.Clean throttle body.
.Get oxygen sensor checked, replace if needed
.Get spark plugs checked. Replace if worn out with original iridium tipped.
.Get fuel filter and fuel injectors inspected
.Get catalytic converter cleaned from a pro if needed, NEVER with acid though !
.Use 0w20 to max 5w30 full synthetic API SN engine oil

You can also try pouring liqui moly fuel system cleaner additive and liqui moly fuel injectors cleaner.

They're poured in full fuel tank.

So do it has 1kr-fe I3 2nd generation?

All these things done already except AFM-TPS, still problem exists.
