Idle problem
 

Been having problems with my car... hunting for revs to nearly stalling and idling up and down, so I've just taken the pipe off the dump valve tip and it idles fine, any ideas what's going on?

Yes if your running a vta DV

Was running fine on old dv then changed to baileys and popped the maf and now even when putting old DV on it still idles up and down

Put the oem recirc valve on and reset the ECU

Not got one as came with a DV and was running fine till changed

baileys DV are known to be rubbish,is it brand new?
Probably leaking air causing poor idle.
Can I ask why you changed the old one out when it was running fine?
Btw I won't ever run fine when you run a vta unmapped,it will run rich on throttle lift.

Was mapped with a cheap nasty forge copy very very loud

No was second hand

Bin it imo

���� what are the forge ones like ?

I've got a red baileys,an eBay(forge copy) recirc and an proper forge vta in my garage if you are wanting to buy another?
I've gone DVless :thumb:
The forge copy recirc ran ok,so did the forge vta but the baileys was cr@p.
I mapped with all 3 and both the vta had momentary rich fueling on lift,running ESL so no option to adjust tip in/out as well as some aftermarket ECUs
