idle problem

First thing i thought was the engine going bad but there were no smoke or oil on the road behind. So I pulled on the emergency line and tried to start the car a few times. At last the car started and suprisingly the CEL was gone. We started driving again and this time i tried to rev the car to 7200 @ wot. It was reving nicely until 7200 and this only happened after the CEL was gone. I also installed a ATS clutch yesterday and made sure that the new flywheel is installed correctly to eliminate another possibility.

unfortunately it came back...
At high rpms the car goes uber rich whatever i do. Even while the stock ecu is in control and the car is off-boost, after 6000 rpm, the AFRs are below 11.0:1 .

my car wont start sometimes, as well as the guy who had my motor in his G before. it takes a little bit of time every once in a while after i drive it hard and then turn it off.
will you post up a nice log in 4th gear from 3000 to rev limit,
i will compare them to my datalog and see how it looks
my car is running perfect, with one street tune run i managed (somehow) to get my AFR from 10.8 to 11.4 along the whole RPM range. will be leveling that out today...

that can be because of colder plugs. my car doesnt start if i dont blip on the throttle when it is hot, no matter how long i crank it. When it's cold, it starts instantly.
ok here is an update,
we pulled out the engine yesterday and today i uninstalled the front timing case. Ta-Da! the main timing chain was not in correct position. The orange link on that should match with the sign on the crankshaft was 1 teeth ahead!
I strongly believe that the problem of my car was because of this "little" mistake done by my ex-mechanic. Anyway, I'll let u know when the car is ready to drive (which will take 2 weeks as I'm installing new heads, bearings etc)

Ive made some changes to the tune and it sounds better at idle but havnt driven enough to test if its worked.
Are you running a UTEC?
