Until now, in 6 years, the car didn`t need any repair or engine tune-up. Everything worked fine - all I did was the regular maintenance ( actually I did the oil change on shorter intervals ), and I drove it easy - without racing or demanding too much from the engine. It`s a cheap car, so I don`t have high expectations from it - I just want it to run and not to ask for money
.
I expected the lpg system to be self-tuning, as the car engine is, especially because it is an expensive model, and it`s installed using the car`s software.
