Is it dangerous to keep driving with this wiring faulty?

Not immediately dangerous, but continuing to drive with a persistent misfire can send unburnt fuel into the catalytic converter, causing expensive damage — repair promptly.

Can this wiring be repaired instead of replaced?

A specialist auto electrician can often repair a localised connector or wire fault without replacing the entire harness.

What is the wiring made of?

Copper conductors in heat-resistant insulation, given the proximity to the engine.

Frequently asked questions

Both a bad wiring connection and a failed injector can produce the same symptom (a misfire on a specific cylinder), so a mechanic will typically test the wiring’s continuity and connection before condemning the injector itself.

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.
