i had a vacuum leak on my passenger side leading to the intake manafold all those vaccum lines all bunched together the top of it was open so i closed it off with e-tape and wow wut a difference. made my truck feel like it had alot more power. i was amazed on how a simple small vacuum leak would rob me off power i didnt even know i had it till yesterday i fixed it and was ale to light my tires up like the fourth of july! and throttle response was way quicker

can you get a pic of where the leak was?

ask and you shall recieve. this piece should of had a cab on it like the other one on but it did not. there is a alot of lines going into each other on the passenger side by the tranny dipstick. to the right it has a spot where they all attach to and goes into the intake manfold. i looked and looked i saw no lines that were off

Shouldn't the fsm have the vacuum routes in it? You could check and see if that is supposed to go somewhere

That part you taped up should have a vacuum line attached to it coming from the firewall to your blend doors under your dash. Do your heat/air blend doors work properly?

Wut do you mean? Ive looked several times i couldnt find any wire or hoses that didnt go anywhere. My heat work and my air conditiong works just does not come out my vents on my defrosters. But that hasnt worked ever since they replaced my dash

Here is a photo of what it should look like. I drew the arrows to show that the vacuum line that runs from the spot that you taped off goes through the firewall next to the a/c evaporator core. Whoever replaced your dash broke that vacuum line (probably by pulling it through the firewall when they yanked the dash out, and they didn't replace it. That is why your defrosters don't work and why that line is open that you taped off.

Thanks man. That helps me alot. So that is y my air conditining dont wrk anymore. It will only blow out defrosters. Also that is y i couldnt find the line that was sapposed to be there. Thanks again if i cant get to the line wut do you recommend me doing?

man i just checked ur right. i have a hose there but its broken and really short any suggestions on getting it hooked back up as it will not reach! just looking to figure out how to add a piece of line to hook it back up?

Use some regular rubber vacuum line. You can buy it by the foot at any parts store.
