Under the hood I got green plugs and white plugs.

 

When do I plug the green ones in (set timing and read codes & ?)

 

When do I plug the white ones in ?

 

When do I plug both sets in ?

88 wagon,EA-82, SPFI,

I had a bad EGR solenoid so I got a spare off my parts rig and replaced. (tested good in resistance and operation.) Now code 35 Purge valve code is flashing however that tested good with resistance but I didn't check vacuum lines and power it up (click, click) so I will do that next.

 

I set timing with green and white connected and stumbling very bad.

Had been acting up a bit but now seems worse. Plug wires are tight but I could use a new set and have new plugs..... I have to feather the gas to build rpms. This has been acting this way for some time and getting worse so figure I better dive-in. Took EGR valve off and cleaned, tested good and installed with new gasket.

When setting timing on fuel injected models Chilton book states to assure the Idle switch is ON and go too section 4, then too connect the green connectors. How does one assure the Idle switch is "ON"....

 

thats all for now...whew....

Yes!

I do not know. They probably work separately.

Now code 35 Purge valve code is flashing however that tested good with resistance but I didn't check vacuum lines and power it up (click, click) so I will do that next.

I do not remember the code for the purge control solenoid. Look for codes in the "Repair Manual" section of this site.

Purge control solenoid is a different one. It is located in the same area where the EGR solenoid is. Looks a little different: no button on it. The connector is blue if I remember it right.

As far as I know you do not adjust idle speed on Subaru. Do a search for "idle" and you will find a lot of information for this.
