Just wanted too see what works for everybody, I run without my EGR, smog pump, vacume advance, I pretty much have all the vac lines pluged up, and i get 23 MPG, the only issue is it dies when engine is cold, other than that it runs like a champ- curious too see what the everybody has capped off-thanks

Why did you disconnect your vacuum advance??? The other stuff kinda makes sense...but if your ignition doesn't work properly, it won't run worth a damn. Set your timing accurately and then hook it back up and you will have more power and it will get better gas mileage.

my vac advance or something is bad, when I had it hooked up, i was getting around 15mpg, i have the timing set a little high and run without it, it runs like a champ and i get good mpg 23 in town 25 highway, im not complaining.....oh yeah--it has plenty of power as well

Get your hands on a hand-held vacuum pump, check the spec's for your distributor, and then take the cap off, take out the rotor, remove the metal cover (if it's still there - and if not - get one) and pump up the vaccuum pump to see first if your distributor is moving (advancing), and second to see if the little rubber diaphram in the vacuum advance is shot and leaking like hell, or the arm connected to it is rusted stuck.

That could give you a huge vacuum leak, really lower your mileage and performance, and can easily be fixed by replacing the vacuum advance. Most parts store still stock them and it's pretty common for the older japanese vehicles to have them go bad.

Also check to see if your distributor weights are moving freely, the springs are good, and everything else is OK, while you've got the cap already off.

If you're gonna drive it...it's all there in the manual...so you gotta buy it, read it, properly diagnose what's wrong, and fix it all to keep your truck running smooth.

thanks for the info, i'll give it a shot---
