Got into some puddles and mud today...the truck was running fine as we drove around. As is normal, the engine got a muddy water bath as we spalshed around. I didn't go into any deep water or anything like that, just muddy ruts and puddles. Anyway, after getting back on pavement, and driving about three miles, the engine lost power, almost to the point of stalling. After that, I couldn't even get to 30mph (and that was only downhill). The air filter was soggy, so I removed it to let it air dry. What have I done and/or what should I look for? It's been drying now for almost 5 hours and still not enough power to drive it. It starts OK though. 99 D2, 90k miles, otherwise running great 'til now. Thanks, Kenny P.S. This happened once before, but after I lost power, it cleared up about 5 minutes later. | ||

Kenny first I would check your oil make sure that no water entered into your block. If it will idle I would let it idle for say 10 minutes the heat from the engine will help it dry. I am not sure where the ECU is on a 99 if it is under the hood or not but with luck the heat from teh idling may dry your problems | ||

Could have been the fuel pump connection located inside the driver side, rear, fender well. If it gets wet it will act up. Try and unplug it and let it dry for a while. | ||

How're you're idle and throttle response? If bad, it could be that your TPS hit the fan. Also, if the TPS goes bad while the throttle is closed, the engine will only reach 1750 rpm before it cuts out the flow of fuel (which could explain the 30 mph). Might want to check that out. | ||

It is time to change the oil, but I don't have a new oil filter. I guess I could drain the old one and use it for now until I can get the car running again. I'm thinking that even if water got into the air intake, the filter bloacked most of it - so where would that bit of water end up in order to cause this loss of power? Idle is OK - I noticed it does "sputter" slightly while I'm starting it. After it starts, I can't get it to rev beyond 2000rpm. I'm assuming TPS means throttle position switch? It's been drying overnight, so I've lost hope in the theory that some electronics got wet. To make matters worse, my better half is now recommending that we get rid of it for a mini-van. It certainly is irresponsible of me to put our only vehicle in jeopardy by taking it off-road. All I need to do is keep the rover in decent shape for 10 more months or so. Wish me luck! P.S. Any more things to look for are appreciated. | ||

You should have been at Brett's house yesterday. Where did you get all this water? | ||
| Kenny Bissett (Jetson) Member Username: Jetson Post Number: 123 Registered: 07-2003 |
Update: I disconnected the battery for 10 minutes, now when I start it, I have no check engine light. But the response from the throttle is bad. When I hit the throttle, it sputters (hesitates) and I can't rev past 1500. However, if I very gradually add throttle, it will rev up normally. Charles: I was thinking the same thing as I sputtered home. The mud at the Den right now has brought out all the trucks. I'm guessing it will be crowded today as well. The water came from the puddles everywhere, nothing deep but if you hit em too fast you're gonna soak your engine. Kenny | ||

Kenny I did the same things with my Disco II. It turned out that the MAF-Mass Airflow Sensor- was ruined when the water touched the sensor. I would check to see if any errors are being brought up on an OBD II reader. I'm trying to remember exactly what codes were brought up. One of my engine banks was running to lean or rich, codes P0171, P0172, P0174, P0175, (not sure which ones sorry) because the MAF sensor wasn’t being able to regulate the air to fuel ratio correctly. I would appreciate anyone who could clarify this. In the end, I replaced the MAF, the air filter, changed the oil, and added a safari snorkel to avoid inconveniences like that. Now everything works like a charm! FWIW Davis | ||

Davis is right - its almost certainly your MAF sensor. You don't have a snorkel (yet!) do you? You've likely got some crap on the MAF filament. Before you buy a new one ($$$$) see if you can clean it by spraying something like electrical cleaner (NOT WD40), maybe someone else could advise this part. Do you know what the MAF sensor is? Its between the air filter box and the engine intake. You can not take the grid off to access the filament directly, so you have to spray something through the grid. Make sure anything you use to clean it doesn't leave any residue when it evaporates. Dean | ||

Thanks Davis and Dean... That actually makes sense and fits with all of the research I've been doing. I've got some cleaner and in fact, if you separate the sextion of intake tubing from the plenum and from the air filter, you can clearly see at least the backside of the MAF. I will do what you suggested and then pick up a new one for the day I get my snorkel. I'm also replacing the fuel filter because it'e been 90k miles! Although the MAF definitely fits the symptoms and the scenario, whereas the fuel filter only fits the symptoms - plus it' scheap to rteplace. Kenny | ||

Sprayed it from boithe sides with no luck. The stupid thing is screwed in with those star shaped screws - the ones with the hole in the middle! I've got some star screwdrivers, but they have a solid center! By the way - where in the world is the fuel filter? Is it inside that black box under the rear passenger seat - next to the frame?

No fuel filter on a D2. It is located on the end of the pump and is not service item. I think your right on with the MAF. Be sure to disconnect the battery for a few minutes to clear the faults and reset the parameters of the ECU after installing the new part. | ||
| Dean Brown (Deanbrown3d) Senior Member Username: Deanbrown3d Post Number: 1314 Registered: 02-2002 |
Kenny - do you know anyone else with a D2? You could swap it out and see if that really is the problem before you buy a new one. | ||
| Kenny Bissett (Jetson) Member Username: Jetson Post Number: 126 Registered: 07-2003 |
Well - things did not improve after several more thorough sprays with contact cleaner. The other problem is the tool to remove the sensor. I don't have one. I'll have to get out to a store. Do I need to buy this part from the dealer? OR are they generally available? Kenny | ||
| Kenny Bissett (Jetson) Member Username: Jetson Post Number: 127 Registered: 07-2003 |
UPDATE! I'm back! I took the MAF completely out, sprayed it from all different angles with the electrical contact cleaner, and it now runs as expected! I used my dremel to cut flathead slots in those damn star shaped screws... Thanks to all who replied! This is why DWeb is on my Links Bar! Woo-hoo! Kenny | ||

Very creative with the dremel....... "Whatever it takes"........ Great thread with a great ending.... Awesome board....... | ||
| Kenny Bissett (Jetson) Member Username: Jetson Post Number: 128 Registered: 07-2003 |
One final note...AutiZone listed a part number for an inline fuel filter for my D2. I went down and bought it before I knew that it was built into the fuel pump. I returned it of course and I let the guy know that thie part does not go with a D2 as listed in their database. That makes sense because my Workshop manual doesn't list a fuel filter at all. Just thought it was worth mentioning. Kenny | ||

Ditto with Michael... I've been following this one-- thanks for keeping us updated Kenny. And, yes! Damned good ending! (I was beginning to worry myself). Bill Mallin Web Dood Houston Land Rover Club http://www.houstonlandroverclub.com 2001 Disco AKA "Sherman" |
