Running a little rough

The honda mechanic had a look at this today and seems to think the culprit is the timing chain tensioner which is apparently a little noisy. The car is over 10 years old, but has only done 25k miles. If i do have it replaced, they are happy to charge an extremely reasonable £30 labour, but the part is getting on for £300 including VAT, which seems crazy. I've done a bit of research. Some have said that sandblasting the worm drive can fix a noisy tensioner, and i've also seen the part 14510-PCX-005 advertised on several US sites - including amazon - for around $120 + shipping. Not sure if they will ship to UK. Anyway, i'd welcome any words of advice.
Idle and TCT are unrelated problems...also do yourself a favour if its realy that noisy buy the TCT for the $140 and install it yourself (takes like 5 minutes)...

If i understood correctly, if the chain is not properly tensioned, it can make the engine run slightly erratically. BTW the chain isn't that noisy otherwise i'm sure i would have noticed it myself.

Hi.
I had an issue with my idle going from 2krpm cold to 200rpm when I reved and let off the gas.
I fixed this by pulling the fuse for the ecu backup and then driving for 15 mins. All sorted now.
On a side not, I have just drive my mums brand new TT around her driveway, made me realise just how raw and crashy the S is!

I'd consider going somewhere else for a diagnosis, with all due respect that Honda tech doesn't sound like they know what they are talking about. As said above, the tension of the chain is a red herring (having said that it could be timing related - something like a cam/crank position sensor, but I'd expect something like that to show up on a diagnostic check)
I'd still go with Theheffs advice and check the MAP sensor it's a relatively common problem and Honda re-designed the sensor and include a cable tie with the new sensor.
I see you're in Surrey - if you really want to spend your money on something I'd try TGM in Fleet for a diagnosis (if they aren't too far to travel for you) I'm sure they'd get to the bottom of the problem in no time.

Thanks for the replies. I never got round to the cable tie as i had decided to pass the problem on rather than try to wade through all the different suggestions. And as it is rather intermittent it's very useful for the car to be in the garage for a day or two - under the supervision of a good mate - with all the knowledge and diagnostic equipment. As i said in the original post, the problem was far less pronounced before the valve adjustment so unless that's a coincidence - which it may be - it does suggest that it might be timing related.
