Normally throttle bodies dont give problems, did the dealer say why it required cleaning? I am curious. Was it fuel quality?

What would throttle body have to do with fuel?

You dont think fuel has anything to do with it? Then what would? Lets not talk about mechanical issues as the 9G has a cable operated throttle which wouldnt affect only high engine revs.

no issue with the fuel they say,they tested it.No clue why the throtle body was cleant but it solved the issue and the car feels more responsive at lower revs,this could be due to the ecu resetting when the battery is disconected.

@r2d2 fuel goes fuel line--fuel rail--injectors--cylinder. no throtle body involved.

I wasnt charged a bomb so i didnt fret paid some 850 for an oil filter,window fixed, and TB cleaning.

Rgds,

Air intake > Throttle body > Intake Manifold > Intake runners > Head > Cylinder.

At no point does the TB come in contact with fuel.

My bad. Aware of that, you missed the intake valves.

How about the the spluttering at high revs that may have caused unburnt fuel to back up into the manifold. I am just thinking of what can cause the throttle body to misbehave.

Thanks Paras211. Good to know it didnt cost a bomb to repair.

Oil companies keep a very tight check on the distribution system and the pumps distributing premium fuels. However no system is fool proof and there are enough people who will adultrate at any cost. But chances of adultration in premium fuels are less.
