So my truck was idleing real rough...and we brought it in. we learned that it was a vacuum leak, and I also needed a new radiator because of a leak. But, after they fixed it up, it started to stall, and still ran rough. He kept it overnight, and said I that I would need a new Computer system that runs the truck or somehting like that...All i kno is $1100...Can someone possibly explain that a little more clearly to me, Maybe a link or something to a website that sells them?

Any help would be appreciated!!!

 

I'll say this, RARELY does the computer go bad, exception would obviously be if the truck was under water, in which case you'd have more than just a comp. issue. Usually when the answer is a new ECU the diagnoser has no idea what the problem is and decides to throw a new comp. at the problem. Also $1100 sounds about 2-3 times what a new comp. should cost IMO, they are incredibly easy to pull out so labor should not be an issue.

One thing to do would be to totally wipe the stock comp. (unhook the positive cable and turn the lights on or just unhook the battery all together for a while to drain the truck) then hook it back up and start the truck, if all the factory defaults work the truck should run without a CEL for a short while until the codes get thrown again, then check the codes. If you have a tuner you can also wipe them all that way and see what new ones pop up.

As for a plaace to get new ones places like NAPA should easily be able to get them but they will need the computer code on yours. It is a sticker on the box and some are also in/on the P. side door.

 

I think I would get a second opinion, like go to parts store that offers free diagnostics and see what codes you get and post here for evaluation

 

Well, We found that pricing to be ridiculous..and we found another guy willing to do it for $350. he said it should also fix my transmission's shift points that are messed up.

Do you think it is possible...that going through deep muddy holes with my truck coulda fried my Comp?

 

Deep muddy holes can do a whole lot more than that. How deep were they?

 

Well, They were more water than mud, thats what worries me..I'm not sure how deep, but i Did have mud everywhere in the engine bay, hood, rood, and bed.

 

The truck is designed to handle water up to about the axle. Water deeper than that can cause havoc with the transmission and your differentials. Anytime you go through deep water a check of fluids is needed. For your computer to get wet, the water needs to be inside the cab.

 

It wasn't in the cab lol, But could driving kinda fast through them cause the water to get up into places it shouldn't be? Sorry about, all the questions...I just wanna lear for the future.

 

Driving fast shoves water into seals and connections. Sorta like taking a pressure washer to your connections and seals. They (the seals) do a great job of keeping fluids in but they are not designed for keeping fluids out. People that off-road through the muck make it a point to change seals and fluids after rough outings on any make.

 

Well, Thats good to know. Thanks for that...so you don't think that coulda effected the computer?
