Ok heres the deal, my truck has ran perfect (other than needing sea-foam badly) till 40k miles and now the check engine light comes on, Other than oil changes I have never turned a bolt on the motor. Im taking it in tomorrow to Ford to have them plug it in. Its a 2002 with 40k miles... Im thinking it probley needs quite a few things (plugs, wires, seafoam, ect.) It still runs fine and is actually getting 14.4 mpg city (it has never got over 14 with the 33's) should I be worried? whatever they tell me is wrong, im going to fix myself, but they give free estimates... LOL I did notice my low octane ping has gotten bad sooooo i guess its time to do some maintenance on her... ughhh

 

What is that...ugh feel like a newb again.

 

its probably just a bad sensor take it to autozone they will check the code for free then you can replace whatever sensor is bad.

 

x2

 

10 bucks on the egr.

 

post the code.... light comes on for about 1,001 things...

 

Bobby, I think I am there with you on that one.

 

Yeah it could be something simple and easy or something complex and expensive

 

Gas cap.

02 with 40k.

 

Low blinker fluid.

 

Nitrogen is low in ur tires

 

checked it, changed it, replaced muffler bearings also... hmmmm

 

gas cap possibly a 02 sensor

 

Whats the code?

 

could be that Evap line on the driver side by the inner fender well could have poped off i know a few trucks after body lifts that its pulled to tight and need to be rebent including mine

 

Yep mine did the same thing, code was a P0456 if I remember correctly.

 

take it to autozone and get the code read for free, screw taking it to the dealership

 

X3, that happened to me on the 04 after the body lift

 

ill check it out tomorrow. Thanks guys! going to autozone on lunch!

 

woohoo autozone lol.....yea they may just give you a print out of the code with a few probable causes which most of them say ur car is gonna blow up pretty much.

So post the code and I'll tell you what that code most often ends up being

 

Forget about it.

I always just let the truck worry about it's own problems. usually solves it's self

 

What does the EVAP line look like? I read up its near the battery, I can't seem to locate it? I just body lifted my truck about 2 weeks ago and my check engine light came on this morning.... Figured I would bring this thread up again instead of posting a new one..

 

bump.. anyone know? Thanks

 

if it's the same as a 97 it's just normal rubber vac line with a couple of solenoids/valves placed in line; attached to the charcoal canister usually behind the driver's side headlight. CEL .. u need the code(s)...
hope this helps

 

I'll bring it to autozone this friday and have it pulled.. I read in quite I few threads about this happening about 2 weeks after people have body lifted there trucks.
