2008 Camry Altise Sedan AUTO

[Andy_Pandy]

G'day Gents.

ODO: nearly 140,000KM

It doesn't feel well while I'm driving.

Took few seconds to accelerate when i push the accelerate paddle.

The left speedometer was a bit higher than before.

The first time starting the engine is a bit noisy and difficult in the morning.

Feels like the piston or cylinder is sucked inside the engine.

Just had service, changed transmission fluid.

Using Petrol injector cleaner liquid at the moment.

Does anyone know what the problem is and how to deal with that?

(Drove fancy sports car before, like Maserati and Labmo, I know the feeling of acceleration can't compare with camry, but at least, I just wanna make camry back to normal, smoothly & automatically change gear)

Really appreciate.

Ta .

Someone said that I should reset/reflash ECU. Should I? Gents.
