Okay guys recently Ive noticed my truck makes what I describe it as a "hiccup" hesitation at start-up. It never happens in the summer but it does it quite often now even when the engine is warm! And the average temp right now is -5C. I didnt have this problem last winter when it was crazy cold!

My injectors are good too I replaced them last year and that resolved my hard starting issue i had back in the day! I also have a fass and put in a new fca. Some fellas say its normal but i dont think it should make this sound after the engine is already warm. It sounds like its progressively getting worse.

P.S No codes!

Heres a clip!

 

did you ever figure out what was causing this? My 04 is doing this same thing?

 

Mine occasionally does the same thing, it has done it pretty much since day one. I don't worry about it, I check the oil religiously at every fill up. I guess as long as nothing changes in the way it runs and I don't find the engine "making oil" until I have a reason to worry I will just live with it.

 

Nah man I dont notice it anymore. It starts perfectly in -30c without any noise so I'm pretty happy with it!

 

Mine has also done this every now and then. I normaly just go burn the carbon off the injectors and don't have anymore issues. I comes up when I have been grandpa'ing it around....LOL

 

Yea I here ya!
