So I done a full samco hose kit on my v reg 2000uk turbo, after putting everything back together had check engine light which was code 23! Long story short after 2x eBay jobbie mafs she still wasn't running right bad idleing and cutting out. I've now bought a genuine maf from Subaru and idle control valve a o2 sensor and a coolant sensor and I still have this slight hesitation on idle it's much beter than it was but it's still there I've only let car run on idle outside my house after all these parts have been fitted I've read the car needs to do a good 20 miles to reset it self ,, ivecsldo left battery of all night and reset ecu no codes on dash all clear also ive replaced the vac lines can any one share some light anything I've missed off ? Car is standard new walbro fuel pump fitted 4 months ago only seem to had this probl sinse I changed coolant hoses was perfect before I started changeing parts .... please help me

Strange it only came on after the coolant hose change or maybe that was just a coincidence.

Yep I know racking my mind with it going to get a smoke/boost leak test on it can hear a slight hiss comeing from top mount/ dumpvalve area

Dont know if its relevant, but after my ICV was changed I did an ECU reset. However it idled really low. I had to take it to Duncan to get it re-programmed in the ECU so it idled at 750. Once done, it worked perfectly.

I think my car was originally setup with a duff ICV, so putting a new one on made it idle way too low even after bat disconnect

It's funny you say that's as today I noticed it idles slightly lower with the new idcv I might just fit the old one to double check as there's nothing wrong with it .. that's a good shout thanks
