Hello,
I just got my first Defender TD5 hcpu. have been driving a series 3 109 for the past 20 years. I found myself a 2002 with 220000km on it, all in very nice shape and got it for a decent price. One thing I've been noticing is that whe I start it or come off throttle to idle. It will idle very rough. Usually picking up sooner or later to a normal idle. But then again if i blip the throttle or come off it into stop lights or so I am there again, waiting for the idle to even out. I cleaned all the sensors, did not find any oil in the loom sensor. No difference. Then while running i disconnected the AAP sensor attched to the air filter box and the idle evened out immediately. Now with AAP disconnected it will rough idle for 3-4 seconds and then even out and the rough idle is not even as bad as with AAP connected. Tried with another AAP sensor from a disco but no difference. Where should I start looking for sollution here? I know the series 3 stuff very well and 200Tdi as I run one in my series but the TD5 is all new to me. Love the car already though, except this rough idle feature I cannot sort out.
