I have high (2,000) revs when starting from cold in my 2003 petrol verso. This is a recent development and my local Toyota garage says not a problem! I disagree. Have changed air filter and checked sensor in air filter feed pipe (it's hell without manuals isn't it!). When warm, no problems but when cold the revs can fluctuate by as much as 2-300 revs (going from say 1,500 - 1,800) when stopped at traffic lights shortly after cold start. Any ideas? The car has 35,000 on clock and owned by us
