Up until about a year or two ago, it had been a good, reliable little car. But the last 18+ months have been a bit of a nightmare.
Anyway... I'll put some cleaner in the next time I fill up. I've been trying not to flog it just worried it might do some damage but I''ll give that a try too.
And I'll get someone to check the spark plugs. How often do spark plugs have to be replaced?
