I just bought my 06 XLT with the 5.4 around a month a go and sometimes when i am stopped at idle my truck has a dieseling effect. Is this normal to our trucks or is something wrong. Only thing i have done is put in a K&N replacement filter. But i think it was doing it before i put it in. Any ideas?

 

if your talking about the tick its most likely the injectors. they are loud on these trucks. can you describe the noise?

 

IT sounds just like a diesel but just not as loud cant really think of any other way to describe it.

 

Sounds like you have a case of Cam Phaser replacement syndrome!......

 

Well if that the case it goin back to the dealer it still under warranty...

 

Well My truck go to the dealer Monday morning. Hopefully nothing is wrong with it, wish me luck. Just glad it under warranty.

 

I've always thought mine sounded a little diesely as well. I've had it for almost a year and have never noticed anything wrong, per say.

 

only had my 2004 since May, but I also recognize a faint dieselling noice when idling sometimes....... maybe I'm just wishing I had one.......

 

Well i might just be paranoid but its better to be safe than sorry.

 

Dieseling is where you shut off the motor and it keeps running without a spark. Doesn't sound to me like your truck is dieseling.

 

I just couldnt think of any other way to describe the sound thats all. It just sounds like a diesel at idle but its fine when i drive.

 

I gotcha... I just didn't want to see you take it in to the dealer and have them check out the wrong problem...

 

Thanks for looking out for me. Yea i took it to them and explained to them the problem. They're just going to hook it up for some test. They said it might be the cam phasers or the hydrolic valve lash adjusters. But we shall see.

 

Well just got my truck back from the dealer and it was the Cam phasers and also the lash adjusters. Just wanted to say thanks guys.
