ICV

[tunnie]

low voltage usually means its buggered.... but what you describe could be the problem. If you have a leak on the exhaust this would cause a number of things:

1) crap fuel consumption!
2) lumpy running (i suspect the ICV is fine)
3) would also be noisey i would imagine??

Try cleaning the ICV, but i suspect your zorst to cat join is the problem

i will do both tomorrow then! hopefully the exhaust wont be too involved and wont need parts!

its not too noisy to be honest, just sounds a little bit "throaty" i only noticed while looking underneath it, i had just started it and noticed steam and condensation dripping from the joint!
