2022 LDV G10 Pricing and Specs

It depends on which particular version of the G10 you have. That’s because, around this time, LDV offered three different engines in vehicles badged as G10s. There were a pair of petrol engines – one turbocharged and one without a turbo – and a turbo-diesel. Both the turbocharged petrol and the turbo-diesel used a timing chain, while the non-turbo petrol (which had a capacity of 2.4 litres) used a rubber timing belt.

As such, the two engines with timing chains should not need maintenance in this area, while the 2.4 petrol’s timing belt will need to be replaced at whatever intervals LDV specified. Workshops dealing with these cars seem to recommend a belt-change interval of five years or 100,000km, whichever comes first.

It’s a bit hard to imagine how removing and replacing a transmission could make an engine misfire or backfire. Unless, that is, you’ve managed to bump part of the engine’s electronic controllers, wiring, sensors or even something as simple as pinched or displaced a vacuum line somewhere in the engine bay. Incorrect ignition timing can make an engine do this, but, again, that’s nothing to do with the transmission.

It could even be a complete coincidence. But did the vehicle sit for any length of time while the transmission was being fixed? You might find the battery has discharged over time. Modern, electronically-controlled engines do not like low battery voltage and can run poorly as a result.

There are plenty of things that can cause this, but being a petrol engine with no turbocharger, it shouldn’t be too tricky to diagnose. Any time an engine runs well when warm but struggles when cold, suspicions are drawn to the fuel/air mixture. A warm engine needs a very different mixture to a cold engine, so modern engines have sensors that monitor the engine temperature, the air/fuel ratio and how well that mixture is burning. If any of those sensors are not telling the computer everything it needs to know, poor running can be the result.

But it would also be worth looking at the air intake side of things. An air or vacuum leak into the intake manifold can also cause rough running and hard starting. The engine’s stepper motor (which controls the idle speed) could also be at fault, but could also be the victim of one of those non-working sensors.
