Sorry in advance for the long post,
I did a few searches and came up empty handed. I tried adjusting my timing by myself and it's at 12-13 BTDC at idle. A hair one way and it's at 15 and a hair the opposite and it's at 5-6. I decided to leave it at 12 and test it. What's happening is the car sounds like a subaru for the first few mins idling and smooths out. But then the first 10 minutes of driving are rough like a subaru, is slow to rev, slow to boost, and is very weak. It doesn't smooth out until I hit a long stretch and keep the rpms steady for a few mins, at which point the everything goes normal and the car runs PERFECT! What's strange is the turbo is very audible all of a sudden, like it just woke up. Park the car, kill the engine, let it sit for 30 mins, the temp drops completely. Start car and it sounds like a subaru--have to drive 10 mins again before it's normal.
Timing is the same at 12-13, no overheating, so i don't think it's the problem.
I can't find any vac leaks.
Burped coolant
I do have CEL 71 (EGR) Euro spec car on USDM ECU (ordered 10k and 2k resistors).
ATS Built 2.0 SB and head with shimless conversion and GSC 268 cams/adj gears
stock injectors
3" turbo back
New dizzy, cap, rotors, coil, igniter, plugs and plug wires, new walbro pump, new fuel filter
Only thing I can think of is I'm coming up on 100 miles since the build and need to retorque.
Any ideas what could cause this behavior?
