I have been trying for over 3 months now to find the problem I have which is the cold start idle problem,running verrrrry rich,misfire under WOT and rev hanging.

Just to recap on what has been done

Maf changed 3 times
2 x water temp sensors (ECU sensor)
2 x oxygen sensors
2 x ICV
1 x TPS
Vac lines changed and checked
Timing Checked
Air filter changed
ECU changed 3 times
Sprayed around intake manifold with card cleaner to test for leaks.
New Coil packs and plugs

Just to recap again on the problem cold start idle is very low 400rpm tries to stall every 10-20 secs once warmed up ides at 700rpm but all the time running very rich and have rev hanging when pulling up at junctions etc and under heavy WOT and boosting 1.2bar I am getting misfire.

Have you done the coilpacks and checked the sparkplug gap? It sounds like you've really covered your bases over and over. Those are all the things I'd have done. Also - which MAF do you have in there. It should have a green label, but I don't remember the number.

Just checked coils weekend just gone and all in working condition.
Plugs all sotted up from over fuelling
MAF on mine is blue which I have confirmed is the right one.

MAF on mine is blue which I have confirmed is the right one.
Oh, okay - well, I could be mistaken. My wife is the Leggy today, so when I get home, I'll try to get a pic, or at least the numbers. I've not paid enough attention to the JDM Leggy's - but I'm wondering if the MAF is the same on all years. Mine's a 94, so it may not help you - but I'm seriously wondering about the MAF - because I've heard that the leggy ones are harder to get (at least in Canada) and things won't run well if you don't have the right one. (Okay, found the thread about my car on another forum, and the specific post about label colours) see it here

It says essentially that he's tried to find blue label ones, but can't for the price, so has gone to green.. so I don't know now.. I'm really curious to know what I've got. His were all wagons, mine's a sedan.. may make a slight difference if they map differently like they do on the impreza's (between sedan/wagon)
Geez, I hope you can find your solution. :(
