Alright so i drive a 95 Toyota 4runner. It's a V6, 4wd, Automatic. It ran fine until i stuck it, up to the floor boards, in a mud puddle. A little water came in the driver side door. It sat there for about 8 hours before i could get it out. What I've done so far is: change the oil/filter, gas, fuel filter, spark plugs, dried the air filter, drain the exhaust and replace the starter. Now what It's doing is idleing very low and shaking. when I give it some gas the shaking stops and it sounds normal up to about 2500rpms. Anymore then that and it loses power, rpms dive. I haven't drivin it since pulling it out, only been reving it up in my driveway. I think thats it, any help would be greatly appreciated.
Thanks
James

when you start the engine, listen for a hiss. the hiss is air getting sucked into the line or where the line should be. vacuum leaks tend ot make a car shake bad. most are the really small lines on your engine.

Cool, ill check that out. I think I saw a map of those hoses on the inside of my hood. If I do find a leak is it just a matter of replacing the hose?

yes you replace the hose. If you prefer follow the diagram and spray carb cleaner on all hoses. when the idle goes up you have found the leak.

I'd be sure to change the axle oil out and grease everything with a zerk down there. Being submerged is very bad and it would be a shame to trash your axles. Take off your distributor cap and see if there is water in there. Even condensation will cause this kind of headache. A lot of off-roaders carry a can of WD-40 with them and if they get a bit too deep they spray some inside the cap to displace the water..

Arggh! Despite these 4X4 vehicles and other bragging about what they can do off road they really can't take it. Some effort is made for bash plates and putting a snorkel (not all 4X4s) for the vent to gear cases. CV joints, u-joints, wheel bearings rubber sealed stuff all over is not intended to be totally water tight but rather be "resistant" to exposure.
Expect brake problems as the dust rubber for pistons of calipers and wheel cylinders will suck in water as they were probably warm and the mud/water is cooler and shrinks sucking junk in.
This needs fast attention to minimize destruction. Up to floor boards is plenty but better than over door handles where vehicle would be about a total loss!
Right now, exhaust system could be full of water too. Again - get on it and get help as needed to save what you can now,

Alright so I finally got a chance to try out some of the suggestions on my truck. I started it up and didn't hear a vacuum leak but I went ahead and sprayed down the lines with starting fluid anyway. There was no reving or anything so I think I'm good there. I pulled the distributor cap off next. It was dry in there but had a few grains of dirt. I cleaned that out. Trucks still doing the same thing, one guy suggested that it might be an electrical problem with the fuel injection system but I don't know where to start looking for that.
Thanks
James

Hope that was a typo using starting fluid! You could have blown yourself up. If an engine didn't fire at all that can be used to spray down throttle body as a test which isn't indicated here yet. Carb cleaner and WD-40 have been mentioned. It may have one or more plugs cancelled out if running but rough.
Most wiring on engine for fuel injection should be higher up than the floor boards but all bets are off. I suggest you get some help to be able to use it if only to dry it out. Brakes may misbehave at first (linings still soaked?) and other problems may or may not come along down the road.
Have any oil holding parts checked for water having gotten inside or change all if in doubt. You are wasting valuable time,
