The first time of each day i start my car, it takes ages...
i sit there and do the glow plugs 4 or 5 times, try to start her and she just chugs, wanting to start but doesnt for about 20-30 seconds. this is really starting to hack me off now. i am aware it is probably the glow plugs but can someone tell me the best way to test these please, and if i should just replace them all.
