    Gurus,

    I was driving normally on a motorway for about 20mins, came off it and drove normally down an A-Road, i had to boost a little bit as i pulled out and noticed a car coming quickly, 3mins later i parked up and waited to pick someone up.

    I then noticed that my idling started bouncing whilst staitionairy from 1000rpm dropping to about 700rpm then back up.

    Heres a recording i took.

    Theres still a few things that i want to get done to her but might have to settle till the summer.

    I want to do the following;

    Clean Throttle Body
    Change the 3 main hoses to either Samco or Forge
    Change the DV to a Forge OEM one, but just have a better quality one rather than the normal plastic one.

    How much would all this have cost?

    1. Cleaning TB will cost bugger all apart from a can of carb cleaner. Very straightforward to do just need a number 5 hex key and half an hour.
    2. Got Samco Blue TIP and Upper Boost hoses fitted, I used JCS Clips, total cost came to £250ish. Fitting was the fun bit; the upper boost hoses were straightforward enough; take off bumper for one of the them and the other one is a knuckle scraper. The TIP I paid some one £40 to do it. You can do it yourself just need time to do it; Danotto did it using the AutoHaus TIP
    3. Personally stayed with the OE Bosch one and have a spare one. The Forge costs about £80 IIRC and fitting is a 10 min job, just unclip a couple of hoses and thats about it.

    You can buy the above from DPM, Awesome and the rest.
