I recently fitted a new maf sensor and that solved my idling problems but I still get the occasional dip in idle, not sure if I have an air leak somewhere, its not a bad dip but still annoying all the same

I got mine from the scooby clinic, paid £120 for the full unit. You can get the sensor itself for cheaper. It got to the point where if I didn't give some gas at lights to stay above idle I would cut out

Have a google on ICVS symptoms..... Might need a clean as they can stick sometimes. My erratic idle cost me £280 for a new one

Ideally you need to take it somewhere and get your ECU read before you go spending money on parts that might not need changing. MAF and ICVS problems would be the prime culprits, but it could be something else too.

It may well be a quick fix, but best to get it on the computer to save you wasting any money.

If your planning a getting it maples then I'd also suggest giving it a good service first, including plugs. You might find that sorts your problem too.

my rough idle was down to a split t piece under the manifold that had a slight split due to heat,

so it may be something silly but get it on a comp before u waste money
