bog standard g40 hesitating at 3/4k

Easy Arnie! lol.

How can you say it isnt a consistant problem, but specify that it happens every time you hit 3/4k? Sounds to me like damp in ignition system if its been sitting a while. Thats where id start anyway.

Also try un-plugging the lambda probe so it puts it into a default mode to eliminate that being a problem

It can be something so much simpler than all those things you are saying! could be belts slipping! especially if they haven;t be replaced for long time!

[hooblah]

turbodaily - i meant its not a constant problem. if the leads were knackered then there would be a problem throughout the rev range and not at a certain point. i'll take a look at the dizzy. it shouldnt be a moisture problem as the car has now been in my garage for a while, where it is pretty dry.

i'll have a go at replacing the charger belts. is it like replacing normal belts or a toothed belt?

oh and whats this hall sensor? someone mentioned checking that.

i wont be able to work on the car til thursday now, so i'll report back on friday. thanks guys.

It may be dry etc, buts its still a good idea to take all the leads and cap off and give it abit of wd40 lovin.

If its still running the standard belt setup, it will have twin v-belts so make sure you get 2. Pretty simple to change tbh, the tighter the better though as they have a tendency to slip.

The hall sender is part of the dizzy, the black 3 pin connector on the top is part of it. It tells the coil when to switch etc.

Have you tried putting a diag computer on it yet? Might give you clue...

Also check the co pot resistance on the 2 outer pins, should be 550 mark i think
