Question about 1998 Mitsubishi Montero Sport

Truck loses power in rain/wet weather

Whenever it is raining outside or is wet my truck seems like it does not want to accelerate. It'll be fine for about a half mile or so then just sort of bog for a few seconds then kick back in. It only does it once or twice then stops and is especially common when accelerating. I checked the wires already and they are fine and the intake has no water in it. I know my fuel filter needs changing real bad and is pretty rusty, could this possibly be getting water in it and causing this problem?

Change the fuel filter. If that doesn't do it then focus on the ignition components. See if there is a code in the computer, clear it and re-read it.

    just changed the filter which took two days in itself and it had mud and water in it. Although I haven't ran it in rain yet im confident this solved it. thanks.

SOURCE: 2004 endeavor problem

Souns like a leak is allowing water into the cabin area, there may have been a leak in the firewall but it looks like it's coming in from somewhere else. Take a look at the rubber door seal in the drivers side door jam and check it for damage or possibile leak area's, if you find a leak here it can be sealed with silicone or you can replace the entire dorr seal. The only other possibility for the leak would be the seal around the windshield, also check this and seal with silicone if a leak is deteteced.

Hope this helps

SOURCE: I have a 1997 Mitsubishi Galant with rough idle

I am having the same issue on Mitsubishi Galant 02. Clattering on acceleration, herky jerky idle. Pulled a code multiple cylinder misfire. My mechanic's diagnosis is bad valve cover gasket causing oil to seap into the spark plugs and bad timing belt, which I have not replaced at 150k miles. I do however know my fuel injectors do need cleaning, he hasn't ruled that out either. Have you pulled any code on it? I have read on engine knock sensor going out on some of these also. Hope this helps some.

SOURCE: missing, loss of power, etc.

I'm sorry I have no solution. The exact sane thing is wrong with mine. I have a 2004 ford focus. It shakes like crazy when I'm trying to go but as soon as I reach a consistent speed it fine. Same story going uphill. Also seems to drive better after driving for awhile except when I go uphill. It started doing this yesterday!

My daughters 2007 Odyssey loses power in rain. It started when she went through a deep puddle coming from work at night. Now whenever there is rain it has little power.


Possible the trip throught the deep puddle soaked the alternatior when water got above the splash guard mounted on the under carrage suggest you check all of the electrical wiring amd relays to see if any are wet or are now exposed to the weather. Good luck. Fixes for deep puddle adventures can be difficult to find and fix.

most likely cause is water intrusion through the cabin filter

pull the filter
if wet then you need to find something that diverts water away

Loses power when it rains or wet outside


The is the coil pack itself? Is its surface clean?
Try reducing spark plug gap, because then the voltage does not have to rise as high.
