This is associated with the "gator won't start" thread. Anyway, my machine is still acting up. As referenced in the previous thread, I was informed that there was moisture in my throttle body ECU. Also, I was told that if the problem persists, that I would need to replace the ECU. The price is apparently $484.00. Anyway, my machine is now hesitant to start sometimes and lacks power when you place it in gear and give it fuel (sometimes). I got stranded last night two miles away from home (without a cell phone) because it died when i stopped. When I returned 30 minutes later with another vehicle and tow rope, the machine fired up. I romped it pretty good getting home and noticed that there was some hesitation in the throttle response when I really got on it. I fired it up when I got home this evening and the same issue was noticed, had no power until it was warmed up (it's about 90 degrees here today). Anyway, I took it around the block (about 4 miles WITH my cell phone) and it ran decent. However, it won't go over 50 miles an hour and never would hit the rev limiter. Looked up the schematic and contemplating just buying the ECU and putting it on myself. Looks like I can save at least $200 in labor. Any comments or suggestions would be appreciated.

Ecu and T-body are 2 separate parts..On my 825 the ECU is up front under the hood...Did you go in water deep enough to get the Computer wet or is it from washing...The throttlebody is attached to the intake manifold, if you are getting water in there, you are taking a chance of Hydralocking your Motor..BAD JUJU!!

On the 850i there is an ECU built on the throttle body. Just got everything apart and will have the new throttle body/ECU on Tuesday. Pretty straightforward disassembly. When I got things apart I noticed that the throttle body had quite a bit of oil in it. Majority was on the top of the throttle body. Looks like the oil tank vents to the air connection prior to hitting the throttle body. I'm contemplating ordering a filter and venting the oil reservoir directly instead of running it into my systems air filter. Any thoughts?
