Ever since it's been cold my truck runs like poop until the temperature in the engine bay gets to a certain point. After posting about 3 topics in this forum, changing a good amount of sensors, and kicking the truck uncontrollably I finally figured out my problem yesterday. TIP for everyone. Work on your truck in the daylight, sober and when the temperature is above freezing! :oops: Well I was looking around the engine bay and underneath And I noticed there was a port on the air box closer to the front on the left hand side(passenger side) that was about 2" in diameter. I had always thought that was where it took in air. Needless to say I later found a hose coming out of what looks like my ex manifold that was smashed under my lower radiator hose. I pulled it out and used a generic hose and two clamps to hook the two up. The original was a type of fabric I think and had plenty of small holes in it. Some electrical tape, rubber bands and superglue later and everything hooks up. Guess what? The truck runs a million times better now when it's cold. No more stuttering and coughing and stalling and waiting 20minutes with the truck warming up just so I can get 3.5 miles to work!!! The original hose is 20 years old I'm sure, and no auto part store here carries it so I guess I'll be going to the dealership this week to get the correct part because I doubt the work I did on the hose will not hold. I'm going to pick up A MAT sensor too because that's about the only sensor I haven't changed.

So in conclusion anybody having problems with stuttering at 1800 RPM's or higher untill the engine is good and warm, CHECK THIS STINKIN HOSE FOR HOLES AND A GOOD CONNECTION. It could just solve all your problems. :D

I'll post back with the price of the hose this week or if anyone knows where to get it cheaper, let me know.

are you refering to the preheater hose that comes off of the exhaust manafold and goes up to the airbox? I was just curious what hose it was, if it was vac hose or not. but glad to read that you figured it out.

Yup, that's the hose ifixit8.

i took that hose off when i replaced my manifold and never put it back on but i didnt notice a difference. I wonder why yours was so noticeable

Yeah I junked mine when I put on the cold-air intake. I have ripped these off of several vehicles. Usually they are useless but if it made a difference on your motor, GREAT! ;)
