mechanical guru's,
looking for some help in solving an issue with my 825i. Bought it new in 2011 and now it has a whopping 175 hrs. It's seen its fair share of time at the dealer and now it is back there for the 8th time since new. over the last two months I've noticed it running rough at idle and you could hear/feel it spitting/spuddering while cruising at low speeds. Sometimes, when you stopped and let it idle it would almost die or completely shutdown. Two weeks ago, it started this routine with me and my 3 year old daughter. This time it started to act up but then the engine went from 1000 rpm to 4800 rpm and stayed there. We were in gear going down a hill. we ran over a few bushes before I could get the ignition off. the Gator would not crank again for several hours. when it did crank, it ran rough again, and the engine took off yet again. I do notice a thin layer of blue smoke coming out from behind during the rough idle event.
I loaded it up to take to the dealer and of course they could not reproduce the problem. It's been there two weeks now. They claim there were no codes and that they have ridden it every day.
my limited knowledge seems to think fuel delivery or sensor related...throttle position sensor, MAP,????????? I have replaced the air filter, fuel filter, oil and filter. I drained the tank and replaced with fresh gas.
The dealership said they noticed a faint electrical burn smell but could not locate where it is coming from. "everything looks good to us".
Any thoughts of what parts to throw at it? or what might solve this issue?
thanks.
Brad
