Another quick question, I've posted it in the engines section but it seems a little quiet.

When cold, the car is fine, revs all the way, and has no problems. However, when warm, and generally when making progress along the motorway it hits a brick wall, like a rev limiter at 3000 revs, nothing can persuade it to go over that. It's a right pain in the rear especially when trying to overtake, any ideas folks??

Thanks in advance,
Mike.

Get the Star codes read. Is it misfiring?

Mike - its not fitted with a speed limiter as part of the cruise control is it ?

Bit of a long shot but I had an Avantime that did this - took me a week to figure out what was causing it redface

Good point !

Make sure the orange light isn't lit on the cruise switch

Hi Mike, try changing the air cleaner, read somewhere recently that fixed a similar problem, could also be the exhaust cat blocking up when hot.

Thanks for the input folks.
scratchchin got me stumped this one has, it can tootle around all day from cold to hot along A and B roads, and rev all the way... then...quick squirt down the motorway, on comes the 3k limiter and that's it....give it a rest for 15 mins and it's fine again.

No cruise control, so can't be that...

No lights on

New airfilter, no blockages

Have it booked into these chaps tomorrow morning to read the codes.http://www.autospecbristol.co.uk/

My Money is on a new airflow meter, or I doubt it, but may just need a good old clear out. smile

I'll keep yer posted...

How did it go? Was it doing some limp-home thing at motorway speeds?
