Ok so car has been off the road for numerous upgrades and is currently awaiting mapping for Andy Forrest just now and this code is coming up and is idling very lumpy but drives fine.
Am hoping its just due to the amount of work that's been done and un mapped but don't want to turn up for mapping and cant map due to something needing replaced either and wasting a day!!

Old spec mapped was running great
vf48
cold air kit with k&n
3 port
adjustable fpr
3" full decat.

NEW SET UP AND MODS
billet 20g
PE650cc injectors
HDI fmic
catch tank heads and crankcase
solid turbo inlet using fmic pipework with no outlets/returns
bailey chav valve
PLUS all of the above obviously
and new neutral position switch

 

Hi Grant

I would suspect injectors(yours car has been mapped for Pink injectors) or MAF will needs to be rescaled at least

I would double check for leaks,clean MAF and have look on the front O2 sensor if its OK(damaged etc)



Jura

 

yeah was hoping just with having the different injectors in place Jura, have already been told that by someone just wanted to see if anything else perhaps as well.

removed the idle control valve and cleaned the other day and still the same, have checked for leaks and found a couple of hose clamps a little loose so tightened up and still same

 

don't want to just buy random parts on the off chance I sort it, that's not me

 

Hi Grant

I know how is it,happens to us few times when we bought something what we don't need or when we bought wrong part,but now we speaking first with our engine builder and tuner Neil@Slowboy Racing when we buying something

Hopefully this can be only the injectors and yours mapper this will sort this easily,I would suspect yours injectors will needs to be rescaled,but still I would check the MAF is it not the dirty/damaged

I have a small blow at downpipe to turbo felt a little air coming out yesterday, will nip that up as apparently exhaust leaks is first to check in the list so might be that, then vac lines, 02 sensor, maf etc the list goes on lol
