Hi everyone
A question that I believe is easily answerable but I'm awful with cars. I'm hoping this will be a quick fix.
Dad asked to have a look at the car (subaru liberty my09 spec b). He flips the bonnet, fiddles around when I'm not looking (Serviced 3 weeks ago). I find out he checked the oil and other things when I told him specifically not to, and he may have tampered with something superficially.
Soon afterwards when I'm driving I find the drive is not as smooth and the fuel usage indicator shows around 25-35litres/100 when I'm cruising at 60kkn, revving at ~ 1500-2000.
If I step on the gas, it'll go the other way i.e. 6-7litres/100km.
Any idea if somethings been knocked loose/hasn't been placed back properly?
Thanks in advance.
Char
