Mis Fire when warm??

[Keaty 0]

Hi guys. Thougt I would come and ask for your advice again, as you did so well with the last problem I had.!!!

Ok so the problem is a big miss fire (ocassionally) especially if I start the car when it is already warm. 9/10 when I start from cold its sound, but if I stop and then come back say 10 min later it really does kangaroo up until 2000-2500 rpm. Then after that you can feel it holding back sometimes. Its seems the more revs you give it the better it becomes. A mate suggested that the Ecu or should that be coil pack is on its way out? Plugs do need a change as it is due its 20000 mile service, but would the misfire be this bad and only happen occasionally if it was only the plugs.

Cheers in advance peeps.

Hmm, what about leaky injectors? You using redex every so often? My old MK2 8V Git used to have a dodgy injector and used to be a nightmare to get started when it was hot.

evntually got to the bottom of this today.. took the beast into a VW garage for a service and go them to have a look at the misfire. Turns out it was a dodgy earth on the hall sender and idle stablisation valve so not a big job at all. Now with new oil, plugs and this sorted, its fooking flying!!!!!!!!!
