I have a 1993 k-15. Their isn't very many things on it that are stock. I drive it maybe 3 to 4 times a year. Last time I drove it I herd a loud pop and I found pieces to a plastic line that looked like a vaccume line. The only thing I can find missing is on the front of the TBI their is a rubber nipple that sticks out on the bottom of the TBI it looks as if a hose slides into it. If so where does the line go from their?

Ever since this happend the truck starts and runs great at an idle but when I drive it I have to ease into the gas or the truck just cuts out.

Anybody have any clue how to help me out?

 

Is their anyway to post a pic on here so I can show what I am talking about?

 

To post a photo, you can either go to Photo and image hosting, free photo galleries, photo editing or you can upload it to the forum.
I would suggest Photo and image hosting, free photo galleries, photo editing and copying the /img url on here, since the site has limited space for each user.

 

if its a bigger line like looks like a 3/8ths hose goes into it might be the pcv valve in your valve cover. also one of the smaller lines that comes off the tbi goes to the charcoal canister at the front of the vehicle.

mine is a 1990 so it might be a bit different
