Thanks for the tips. I have one quick question maybe you or @OSS can help me with. I’ve been digging through some threads and it seems like a malfunctioning egr can mess up the distributor. If we are assuming mine is broken since it is capped should I get a new egr set up or recurve the...

Found this is the manual as well. I did a half turn of the screw and now I’m idling beautifully. Thanks you for the tips and knowledge man I really appreciate it. Will look into the vacuum gauge

so since I dont need that system, I am assuming I dont need vacuum to that diaphragm to help pull the actuator. So the issue is likely with my carb then, I will have to learn to adjust it next.

Thanks, yea was thinking the same it’s kinda loose fitting the gasket is definitely crusty

this is all I have the driver side border of the engine bay, looks like the line should attach there ac idle vsv, but the plastic pipes are broken. I suppose id need this, even if I dont have AC? or is there someway to adjust the actuator on the carb?

yea I see that the Q line from that top valve is what connects to the EGR line there, they are both capped off. any idea how I can vacuum to that diaphragm? I had this truck at a pretty well known cruiser mechanic and he told me that line to the diaphragm was not necessary as it is for ac, and I...

I plugged those lines seems to be better idle but still weak and dies after a few seconds. my ICS is working, I hear the click and I am getting power to it. When I pull the actuator on the back of this diaphragm I get a good idle with the choke in! now I am trying to see where and how I can get...

yes it does help. thanks, seems there's been a lot of tinkering with this old truck. nothing is where I am expecting it to be.

Hey thank you so much, I guess I was looking at PCV diagram and it was not on that one. with the choke pulled out about a finger width, I place my finger on the hose and it is a huge vacuum leak for sure. I just didn't know where it was supposed to connect to. There is another open pipe in my...

The town which I bought it from in gold country California is about the same altitude as where I am located. About 100 ft elevation difference.

Hi folks, ever since I got my '83 up and running it has never idled well. It runs great with the choke slightly pulled out, but with the choke in it stalls out as soon as I left off the gas. I am not only new to wrenching but this emission system and carb confuses the heck out of me. I've been...
