Ok, thishas been fun beating my head against the wall. Im on engine number three and i think my max is cursed. To make thinks quick heres what happend:
Engine 1: oil leak that got worse until engine developed severe knocking
Engine 2: crack in timing cover. catastrophic breakdown (have no idea what happend. car died on wife as she merged onto highway. mechanic could not turn engine over with at crank plully). Clutch kit, motor mounts and front o2 sensor replaced at that time.
Engine 3: warranty replacement for #2. Ran rough first day, stalled alot. Replaced all coils, and plugs. New rear cat. Got code p0011, p0021. Cleaned Ivt and they were gunked up. Seafoamed engine today. Runs so much smoother and doesnt stall. Codes have not returned.

Now the issue is that from stop to 3k, car doesnt pull hard. like its plugged. At 3500-4k, car smokes a wee bit and moves out really good. what should I look at?
