Thanks for the info, much appreciated.

I shall try testing it over 5k rpm as you suggested.

My car seems to idle a little fast at times, especially when i come to a stop (say at traffic lights) after a high rpm run.

It is also running a little rich apparantly which is causing the high emission levels during my recent test,

I was told this may be the sensors, however I am not receiving any error codes. I had holes in the exhaust but these are fixed. The high-ish reving ad idle seems to be a little worse since these have been repaired, Any other ideas? I have checked airfilter and shall replace the sparkplugs soon through matter of course, I assumed the O2 sensors may be to blame, as fuel economy seems a little low, averaging around 32 miles/gallon. Is this normal?

The car is running fine though, starts fine and is causing me no real problems except a slightly high idle, generally 1k rpm, sometimes it revs up to 1.5rpm and then drops again. It makes the car infront think I am getting impatient

Any ideas would be gratefully received.

Many thanks.
Paul.
