I just bought a 85 with the I6 and it is running rough. It doesnt seem to want to idle and when I stop at the light it dies but will restart. The emissions light is on so I am wondering if I have a vaccum leak or if one of the lines is disconnected.

Does anyone know where I can see pictures or a diagram of how these hoses run? They rebuilt the engine with a new block and it looks like they didnt hook up all the connectors and so I am thinking they didnt hook up all the lines either. So far I have found a green and red wire that were cut at the carb and I dont know what they went to so any help appreciated. I love the truck but need to get it going.

 

You should have a diagram on the radiator support. If you have EECIV on the radiator sticker, then you should be able to run a scanner and get some codes from the computer.
