limp mode in water ???????

[Cummins14]

My truck is a 95 3.0 swaped from an auto to manual 5speed,,,well it runs great but i can not drive through water... at hardly any speed but 9 times out of 10 it goes into limp mode,but comes out of it within a couple of hours (15min to 5hours) help???? (also sometimes goes into limp mode when it rains and im driving...)

[pooleo]

limp mode = water in intake. Stay out of water

Can you define what you mean by "drive through water"?

[Rhodyguy]

Just how deep is the water ?

[blhde]

Define limp mode while your at it, as it sounds like you are getting something wet that is suppose to be sealed.

[FireRanger]

Limp mode is when the computer limits the speed, RPM, and maximum gear based on a detected misfire or transmission problem. It allows to limp home slowly.

Has it done this ever since you swapped to a 5-speed?

yea i bought it with the swap...when i first bought the truck im pretty shore it didnt do it sence in my test drive i went mudden before i told them id take it (just bought it last july)

[FireRanger]

Look to see if you have something disconnected on the intake. Like the top of the air filter box or one of the intake hoses.

[Cummins14]

yea ive unpluged repluged and everything no luck thank tho...anymore suggestions?

[pooleo]

Are you crawling thru these water holes are hitting them with enough force to spray water ever where? because you say it only happens when you hit water, I have to think your getting water into the intake somewhere. Factory air box?

What about the automatic DTRS? Was the wiring changed or is that sensor tucked up in the frame? Maybe its hanging, getting wet and causing problems?

I changed my 97 to a manual. I left the wiring but stuck that sensor in a zip lock bag and zip tied it to the frame.

[Cummins14]

well the first time i hit it going around 30mph but not around 10-3 mph i can walk beside the truck faster than drive in it sometimes and it still does it????anymore help this happens almost everyday

im not shore what does it look like???where is it located and about changing it im not very shore most likey wasnt

Exactly my line of thinking.

It should be down by the frame. I guess about 10-14" back from the back of the engine. Just look for any wiring other than o2 sensors. Being a 95, I dont know if they still ran the A4LD or had the 4r series...

From what I gather from your last post, you first ran thru the puddle at abou 30, and the truck has not ran like it should since....?

I once went thru a flooded part of a street, hauling ass, Got water in my intake and the truck ran like shit for about a week. I think it still had water in the system. Could be a similar situation with yours....?
