I have a Hyundai H100 2.5 Diesel Turbo Year 2001 (Standard) and its recently started chugging while moving. Its as if it is misfiring but the engine doesnt cut out, it just chuggs. When coming to a stand still, the idle time, which is normally around 800 rpm, will vary itself between 800 and 1200 rpm, randomly moving up and down.

Has anybody got any ideas as to what this could be? I've recently had the oil and oil filter changed, along with the air filter but its still happening. It cant be good for the engine.

Any advice appreciated,

Hi BassAddict.

Did you find a soulution to your problem? If so, could you please post your findings?

Seems I have the exact same problem with my H-1. See thread at
