mine used to do that, and it turned out to be a dirty throttle body, so you could try that
also you could try cleaning your iat sensor too, as both of these cause a lumpy idle.

you normally need to reset the throttle body using vagcom after, if you do clean the throttle body that is

Good suggestions but I cleaned the TB and realigned it befor the remap (was ment to say it's just been mapped)

And what's a iat sensor?!!!

Cheers!!

I think the IAT is sensor just after TB and is bolted in with a hex bolt.

[rio_gti]

the one that reads the temp in the mani?

[brewey]

Yeah that's the one. It builds up with all the crap that coats the TB. Worth a go at least anyway. Is you MAF alright?

[rio_gti]

well tbh when I cleaned the tb I also cleaned this sensor and the inside of the mani so it was nice and clean..... ill try the other sensor I got tonight thou....

maf should be alright as its the one they used on it when they mapped it so they should have picked it up if it was faulty

[MoMartin]

Maybe a vacuum leak somewhere? though, they normally check for them prior to remapping

[dom]

I'd also suggest a minor vac leak

Looks like I'm gonna have to DIY smoke test/ pressure test then!!!!
