Choppy Dyno Graph.....
I went with a few mates to get our assorted cars Dyno tested on Saturday. My 2001 2.0 GTV was the odd one out in more ways than one.... Everyone else's dyno graph was the usual staright line climb and drop off. Not mine, oh no. To great hilarity the GTV returned what looked like a cardiogram as it wobbled it's way to a max of 132.5 hp. I'm not that bothered about the power at the moment but anyone any ideas why it would be so choppy? Dodgy timing, dodgy fuel injection, dodgy belts? Belts are due for a change in January by the way. The bloke running the test had never done an Alfa before and said he'd never seen anything like it before - he at first thought his dyno was knackered!
Any suggestions gratefully received. I'm going to take it in for a check this / next week but if anyone has any suggestions it would be a great help!
