Hi, one is an intermittant problem, the other has been fixed but I'm wary of it returning. Firstly, the rear window wiper only works intermittently, are the steering column stalks known to be reliable on these and also would it mean a failed MOT? Secondly, my engine staring running really sluggishly, had been serviced two months ago, my local garage had it in for the day and found one of the spark plugs was rusty near the middle. He said water must have gotten near it, how could this be though, the spark plugs are under the bonnet. I had a look under the bonnet and was none the wiser, admittedly I know nothing about cars. Any idea where I should be looking?
Thanks Pete
