My mum has a H reg Volvo 740 140,000 miles on the clock and recently its not been starting very well. It just about starts but is very lumpy and has no power, about 100m down the road it will sort itsself out and run ok.
Ive changed the spark plugs, leads, distrubitor, its not struggling for air as i have removed the intake pipework and the problem is still there.
Im just wondering what to do next??
Any suggestions welcome.
