I have posted here before & i'd like to thank you all for your help.

Current problem is/was erratic idle, initialy he (my teenage nephew) came over because of that.

I disconnected a lower hose from the intake tube & sprayed c/cleaner into it it worked fine for a few days (turns out the hose i disconnected was the inlet hose for the IACV, so we have a backflushed IACV). Damn me i'm a ford mechanic,(it looked like a EGR valve to me) didnt know any better. Anyway now we have a problem of intermittant no start/dies with no notice. Did i mess up something or could it be multiple problems. Searching this site i have found a KOEO procedure & codes, was just wondering if there is also a KOER link or even if its necessary? Also many people have brought-up the coolant temp sensor on previous threads. Any and all ideas will be considered. Just give me your help! THANKS!!!

What is KOEO, KOER?

 

Have you tried checking to see if any codes are stored in the ECU?

 

Instructions can be found on my site, under notes & tips, engine related

www.surrealmirage.com/subaru

KOEO=Key On Engine Off. That would be the read memory mode (Read memory connector connected) & U-check mode (Test mode connector connected, read memory connector disconnected).

 

KOER=Key On Engine Running. That woud be D-check mode (Test mode connector connected, read memory commector disconnected, drive car). And Clear Memory mode (Read memory and test mode connector connected, start car, jump through hoops, drive car.

Mr. Legacy 777 & Mr. WAWalker,

Thanks for your replies, L777 your site is where I found the procedure to check for codes, however I didnt really read the paperwork enough to discover that both procedures were included, sorry if I posted early. Dont get to see the car till saturday, so no codes yet. WAW your explination is exactly right. Premature (again) but I have seen threads that show? that the c/t/sensor may be the cause. There is no CE/light illuminated. Sorry about the ford terminoligy but thats all I know. Keep the info coming,THANKS!!
