Idle Actuator + Throttle Body Help!

My ongoing saga with bouncy revs continues when clutch depressed and moving at 10mph+ - I thought I'd fixed it with a thorough TB clean but it's now back and worse than ever.
Two questions - can I remove the throttle body to clean again and justy replace using existing gasket? Also if I changed the idle actuator is it a straight swap or do I need to get it reset as well using Alfadiag?l - its a '98 2.0 TS.

Re: Idle Actuator + Throttle Body Help!

I had the same problem.The way I solved it was to buy a secondhand throttle body and install it but when you install it do not to do a throttle reset.It took me a good few goes to get it right.At first when I installed the new throttle body I did a throttle reset and the idle was fine for a day or two.I also used Alfadiag and the same thing happened so finally I tried installing it with battery connected and no reset and it seems to have worked,it's worked fine since last november.My advice would be to remove throttle body give it a good clean,stick it back in and DON'T DO A THROTTLE RESET.
