Got a weird issue with my 2003 V6 4motion with the BDE engine. Anything under full throttle around 2k to 3k rpm in all gears except 5 and 6 produces a strange feeling hesitation in the car. At full throttle it doesn't hesitate at all, but anything less (down to about 20% throttle) will. I've got no fault codes in the engine module and run 99 tesco momentum fuel more often than not. Anyone else experienced anything like this with one of these cars?? No other noticeable issues with the car other than this.
Did a quick test to try and determine my peak power to see if I'd lost a decent amount, using a 3rd gear pull and checking peak air flow (g/s). got 160.3g/s so around the stated 204bhp (I know its not dead accurate but it's the best I can manage).
