Hey, new to yota tech, I have a 87 pickup with a 22r in it and basically, my problem is when I start my truck, it seems that fast idle doesn't work, it idles low and if I don't keep on the gas, sometimes it'll die out and I'll have to restart it. But then once my engine warms up, it seems to fast idle all the time. Everytime I push the clutch in, my idle jumps up hella high. So pretty much, my fast idle is not working when it should, and is working when it shouldn't.. Anybody know what the problem could be?

 

Maybe a vacum issue?

Need help Yota will not self diagnose thru check engine light will not run fuel pump still won't run unless direct wired. could my computer be bad?
Please help!!
