like title states i was just chewin through this mud hole.. welded rear and the mud kings just plowin on through.... then i go to get out of the hole and the yota dies!!! wont fire up until about 5 minutes... i giver heck and back out of hole...and limp back through trail home..

now my revs are going spastic and it seems im running on 2 or 3 cylinders cuz i smell gas.. i get some back firing and sputtering..

i know my brand new o2 sensor got soaked!!

where do i start loooking !!!

next project before mounting my winch is SNORKEL!

please help cause im

im gonna switch the tps and put some new plugs in my my dd..

MY FAVORITE PART OF 4WHEELIN IS COMING HOME TO A CLEAN FUNCTIONAL 4RUNNER!

 

check you distributar cap for water. sounds like thats whats wrong!

 

yep check your distributor try spraying a bunch of WD40 in there, also check your TPS, clean out your AFM thuroughly, clean or longspark your plugs, when you installed the new O2S as long as you used the factory tube that covers the wire you should be fine, newer (since late 80's) 02 sensors draw their fresh oxygen through the hose that surrounds the signal wire so as long as it is still connected the water shouldn't pose an issue to it.

 

ill post pics as or vids when i get them..
ok guy i have a few spare distb caps kicking around with wires.. that and some new plugs and some cleaner i should be good to go.. good thing i have my other 4runner to get to the parts store!!

 

ok found the issue
seems like on 4runners the air intake comes right behind drivers headlight.. when 2 deer ran into me it took out the side lamp... so when i was in the hole coming up with sucked in water and must have got the AFM muddy.. now it runs ok but idles crappy.. cant i take the pins out and clean them with contact clebner or alcohol like electronics?? im already making a snorkel should be an easy fix...

cant believe how well the welded rear and 32 mud tires did... couldn't stop this beast till she choked.. even then she got me out of the hole on how ever many cylinder where working

 

Sounds like you bent a rod. You can use electrical contact cleaner on any electricals.

 

i would wait to see if it all dries out, whenever i go through puddles and mud my truck idles like crap for , but the next day it will run just fine.

 

ya know, everytime i go through a mud hole it seems like i break something( steering gear, C-Vs, stuff like that) but when i go play in the sand or creep down a rocky trail im fine. Now i understand why so many people hate mud. dont get me wrong, its fun as hell to do but i think that im never going through mud ever again unless its between point A and point B with no other options. Just my new philosiphy

meh.. ive done plenty worse and never bent a rod. not saying its not possible.

 

Pull the plugs and crank it over a few times, any water will come out. Change the oil NOW, just incase you sucked in any water.

 

1990 runner I know what your saying, go through mud if you have to but avoid if possable. After last weekend I totally agree.

 

well around here if you want to hit the trail there is some monster holes in them..

ok guys well today I changed oil filter with new oil spark plugs distr cap and wires...
Now i fired it up and it seems to be running alot better but idles crappy.. gave it the sea foam treatment... sure pissed off the locals....ok so now what??? my AFM checks out with my multimeter.. could the tp gotten crudded up with muck since i know it went into the throttle body??? im running on all cylinders again just a crappy idle....


also i can kinda of hear a vacum leak or something so maybe ill get some soapy water see if i can find a leak?

 

when i did what you did it ran like crap for a couple miles but then i got out to the highway and got the rpm's up and it started running better again.

 

yeah im just reving it in the drive way... maybe ill put my plates on her an giver a rip... it is def running good now but just idles crappys.... could my o2 sensor got wet and causeing a bad fuel issue??

I GET NO CHECK ENGINE LIGHT??
