Hi guys k well still trying to figure idle out, but deciede to pull codes again, i usually use test light but i guess i wasn't reading it right so i got one of those digital ones that just plug in. Anyways codes go KOEO= 81,82,85,84 KOER= 94,44,33,13 then said cylinder 8 and 6 don't know what it meant by that one.


Anyways question is about 33,44,13. First i have removed all pollution **** smog/egr. I have that egr eliminator installed that is surpose to be give me code 33 correct? so that i don't get drivability problems?

Code 13 for high idle which i have been having. I unplug iac and it does nothing, but its a brand new iac valve. Also i i checked for voltage at pigtail and got 14 volts while running. Is the iac ground controlled? Wat could cause this to happen since now i am headingin the right direction i hope.

I'm assuming all my 80's codes are ok and won't have drivability issues. since just pollution crap.

Any hlp is appreciated guys.

k well by searching through past posts and wat not. I have read alot of people saying vaccum leaks. I'll look into that tomorrow.

Quick question how does the iac work. How does the computer control it? ground side or power side. Is it surpose to see 14 volts while running. code 13 saying it won't move the dc motor? Is that cause of the vaccum leak? Hope someone can chime in and point me in the right direction thx.
