RS2 Judder/hesitation on acceleration/ Code reading

[naim22]

Hi there, currently enjoying the RS2 and had to take it out for a blast today!

It's going really well at the moment and have had it 6 months now, doesn't get driven loads but makes every journey that more enjoyable

One issue I have at the moment is a judder/hesitation once I hit about 4K rpm, it doesn't happen everytime but does occur quite often. It seems to be worse under higher load and only really occurs over 1/2 throttle.

Having done a bit of searching I am thinking it is one of three possibilities:

- Coil Packs
- MAF Sensor
- Boost Leak

Ideally I would like to read the codes (not sure how useful this is) but I think it would be a good start. Is there anyone in the North Yorkshire area who is handy with these cars who could read the codes or alternatively what do people recommend to do this with myself? Don't think it has a standard 16 pin OBD plug?

If it needs a new MAF/Coils/Hose are genuine parts best to replace or would people advise on uprated aftermarket parts (if available)?

Thanks very much and sorry for the daft questions! still getting to know my way round these cars.

Start with the plugs although I am almost certain your coils need changing

Check your plugs.

Could also be the coils/drivers, if so... good time to upgrade to the new style COP ignition with a harness from Norbitron.

It may also be related to your coolant temp sensor (G62), which you can check the ohm values with a multimeter.

Those are good ideas.

Yeah. First priority is to keep yourself and family high and dry. 2nd = keep your RS2 higher and drier.
