Is it dangerous to keep driving with a faulty injector?

Not immediately dangerous, but a leaking injector is a fire risk and unburned fuel can damage the catalytic converter over time — repair promptly.

Can injectors be cleaned instead of replaced?

Often yes — professional ultrasonic cleaning can restore many injectors clogged with deposits, which is worth trying before replacement.

Should injectors be replaced as a full set?

Not always necessary if only one has failed, but on a high-mileage engine, replacing them as a set ensures even performance across all cylinders.

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.
