ok i know tthis has been touched many many times before but I like to ask so maybe some new information comes to light,,,,,,

I know for a fact from cold start I should get 1500 rpm then as it warms up settles down to 950 rpm or as discussed with Sabre we will re adjust back down to 850 , i like my idle low as my hayward and scott exhuast is really loud and deep and just vibrates the shit out of anything glass or residential lol (so sorry but i love it) HOWEVER - recently having tried 3 different plastic RS inlets

- i am stuck on 2000 rpm cold start - so you tunr the key it revs up 2000 rpm then splutters at 750 rpm then levels out - i mean it sounds kool lol lke a rally car (any temp below 50 Celsius via scangauge) which is effin loud if i have to pick up my daughter from work or uni late , just wanted to know what controls the cold start - i had it perfect briefly but after 2 X 20 mile drives no boost it seems something has worked loose again but wanted an opinion - ie that barometer would that affect idle? Another thing i have noticed , if say its still warming up ad i , say, start to roll out of the drive, the car senses movement and then lowers idle, ive had 3 / 4 different RS ecus and this is the only one that does it - sorry many angles of info here lol ----- does the speed sensor affect idle?

Runnin larger big mAF SO that can be ruled out -
Tried different new Lambda sensor , tried genuine one and euro carparts no difference
Secured all vacuum ports and i mean properly EVEN a hoseclip on the PCV valve lol
New inlet gaskets < new throttle gasket,
Even bought an o ring splicing kit and made a gasket between inlet and throttle adapter
Tried 2 new Throttle sensors new and genuine
Though maybe rail is leaking , changed o rings etc , no change...
Exhaust downpipe not leaking either end....

There was a rev hangup between gears but that was the power steering loom which is now sorted and is good between gears ....

Before i sell it ...or try a Metal inlet any ideas loool ??? cheers people ...

The only thing i can think is im not torquing the inlet properly and working loose - i mean for example - @big_wasa has that RS engine running on a engine stand ... look how nicely it idles loool wyhy cant any of my focus be like that......

I had ONE ecu about 3 years ago which i used to convert my T230 from Pectel to Ford RS Ecu and that was perfect but my engine and turbo was shit so sold it all lol - shud of kept it ...maybe its the AE AF map thingy?
