First post so apologies for wrong forum, misreading rules etc.
I have a beloved and rather pants 1998 astra mk3.
Usual malarky of management light coming on. EGR valve indicated as cause so disconnected it.
Car has run fine for months without EGR connected (though of course management light is still on).
Last couple of months a new problem has occurred.
Once engine is warm (half hour or so) the car will start to rev itself at idle (or when clutch is dipped, e.g. braking to stop). This doesn't seem to affect the running of the car and its done stacks of miles since problem first reared its head.
However, its 1) doing my nut revving at the lights, and 2) scaring the missus who is currently learning to drive in it, so I need to sort it.
The EGR valve is at the back, rh side of the engine, not sure if that helps id the exact model I have.
I don't think the revs are connected to the EGR as it was disconnected for some time before this issue occurred (plus plugging it back in again makes no diff).
Where do I start? I trawled forums but got caught up in throttle bodies, icvs etc. So thought best to find out what model engine I have so I can start cleaning/replacing bits.
Any pointers gratefully received
