Surprise result!

Last week I fitted a new rear disc (along with new pads) - I went for the Brembo Oro disc, with new bolts. Think it took me an hour. Including a full clean and re-grease of the caliper sliders.

But, along with my order from Motorworks, I bought some new rubber caps for the vacuum connections on the throttle bodies.

They looked like they would be too tight compared too they old ones (which, externally, looked perfect). They pushed in just fine.

Well, all I can say is I now have a near perfect, stable idle! I thought it wasn't bad. But now! Yay!

Just wanted you share this little detail as others might benefit

This was after approx a 100mile run to see a customer... (It's only 20sec, but it's representative)

Number 3 and 4 cylinders seem remarkable quiet as well.

Sounds good!

I've never spent so little and got such a big result . In 10yrs I've never once touched the throttle bodies...

Just thought I'd share it because I'm sure it's not just me neglecting them

Do you think those old rubbers caps had perished or grown with time and allowed some air to be sucked in?
Resulting in an erratic tick over.

Well done, improving it, with as you say little money.

The new ones looked like they were going to be too tight. So my guess is, the old ones had gently swollen over time. They didn't look perished though, which is one reason they might 'look' ok, but in fact are leaking.

My previous idle was ok. But subtly suggesting it might be time for throttle balancing...clearly it was easier than that!
