McAlister Fuel Injection Ltd in Cumbernauld, Glasgow

My car went in for a poor running problem, they apparently tested everything under the bonnet, and I mean everything as my bill came to a whopping 300 quid!! I have my doubts as to what was tested as they failed to spot the problem with the car which was a poor flow in the fuel filter housing which I had fixed by a mobile mechanic for 25 quid (car now runs sweet as a nut). They also advised it could be the cylinder head gasket which would cost me 600 quid to have fixed, turns out there is absolutely nothing wrong with the cylinder head. To say I am disgusted by this companies actions is an understatement.
