    Part-throttle hesitance/almost a stutttttter.

    AJQ 1.8TQS with a dodgy Chipped-UK remap.

    Not a problem with accelerating, but on a long run and on part-thottle on the M-way, I feel there is a hesitance, which feels almost like a stutter in the system. Full throttle acceleration not a problemo.

    So is it:

    MAF
    Ignition coil
    Fuel filter
    Anything else???

    MY car also has cruise and therefore a drive-by-wire throttle. Any know problems with these?

    Now I've just got to sort the wires to the radiator fan and air-con compressor, as they intermittantly stop working

    I have a perfectly clean MAF, Clean throttle body, clean filters, new fuel pump and new ignition control module.

    And my car did it too at about 4500rpm. It was the Superchips Remap.

    Worth checking the MAF, I borrowed Nick's MAF put it in my car and it runs fine! See if you can swap one in for a run and find out! Make sure you buy a Bosch part, no a cheap MAF of fleabay trust me on this I am 60 out of pocket because of it!

    Good luck, dam now everyone has posted! opps ignor me!

    Sounds like a map issue to me aswell, transient/over run fuelling.

    Got a stock re-circ valve, new 4 months ago - took of a bailey dump valve to replace it.

    Worth getting a newer one? the S3 version? Is it a stronger spring?

    Got other issues to sort first.

    Just had a 300 mile round trip and the temperature went through the roof when I hit traffic on M25.

    Don't think the fan is cutting in.

    Also need to check the air-con compressor wiring as it's stopped working again. Intermittent fault.

    Double ars3.
