Is it dangerous to keep driving with a dirty or faulty throttle?

Not immediately dangerous on modern electronic systems (they have built-in safety limits), but performance and drivability suffer — clean or repair promptly.

Can the throttle body be cleaned instead of replaced?

Yes, in most cases a proper clean of the valve and bore resolves carbon-related symptoms without needing replacement.

How often should the throttle body be cleaned?

There’s no strict interval, but checking it every 30,000–50,000 km, or when symptoms appear, is common practice.

What is this part and why does it matter?

The throttle valve (throttle plate) opens and closes to control how much air enters the engine, directly controlling engine power in response to the accelerator pedal.

Frequently asked questions

Carbon deposits from crankcase gases and fuel residue collect on the valve and its bore, restricting airflow and preventing the valve from closing to its exact calibrated position, causing a rough idle.

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
