2002 A4 2.0 Petrol Spluttering

[yagayo83]

Done a service on my car last week and then 2 days ago I tried to start the car and it's very splutery when cold sometimes even very hard to start. In the morning when its cold and you try to rev it if you rev it too hard it cuts out and when its cold and you change gear theres a major delay in power that was never there don't know much about mechanics but it seems to be something with the airflow but I'm not sure..Can anyone help

if you had the air trunking off between air filter and throttle body maybe not sealed that correctly also there are various vacuum pipes located around there, if you can hear air hissing concentrate on that, otherwise check you got plug leads on and in correct order other than that you may have cracked a plugs insulation ceramic thats easy to do! been there done it. good luck mate

I got the car put on diagnostics today and when it was cold the fan was comin on and it was reading that it was over heating we looked at the back of the engine and the water temperture sensor was leaking..so I replaced that hope that was the problem...Have you ever heard of this problem??
