I have not driven this all winter....Has had chk eng light on for a long time and I am positive

it was a code 34 which is the egr valve or circuit

 

I hooked up the battery this weekend as I want to sell it (has 54,000 original miles and nice shape)

I was getting 7 flashes with a pause and the same 7 flashes over and over again

 

There is nothing that shows 7 flashes

 

Can someone remind me of what connectors have to be hooked...it is under the dash up behind the ecm right>? (black?)

 

Can the code be cleared without fixing it? to see how soon it may come back?

I am thinking no

If I get a new egr solenoid....how do I clear the codes then? 

 

More importantly....can this egr solenoid cause any rough running condition??  It runs good but not 100% right...mild stumble of the engine

 

Note that I have the egr valve off and a metal plate sealing off the opening --used RTV to seal it....and hose is capped off

thanks

 

the check plugs for the ECU are two green connectors that don't have locks, so they dont lock when plugged together.. should be right underneath ECU

 

and not sure on the EGR, maybe someone with carbed or SPFI knowledge can chime in to help you

IIRC, 7 is a calibration code (i.e. SPFI, Cali emissions) and not an actual fault code.

 

Checking the codes w/o any connectors connected will display drive-ability codes or active CEL codes.

 

Hooking the green connectors together by the fuel filter under the hood might bring up a few non-critical codes and connecting the white connectors next to the green ones (white connected only), then the LED will display old codes.

 

I had an intermittent code 34 (EGR solenoid) before it finally gave up and the solenoid failed. Might just be having a good day with this one and there are "no problems"
