I was having trouble with my idle staying around 2 to 2.1K with the occasional drop back to normal. I tried adjusting it and read a lot on D-Jetronic FI. The next item in line was to clean the decel valve but I thought I'd wait until after this weekend's run through the mountains for fear of messing it up and missing the drive. Well, when leaving a friends house I put the trans in reverse and backed up but then forgot to put the car in 1st before starting down her drive. I let off the brake and coasted a little ways down then let out the clutch to slow the car. The engine stopped running, turned backwards, spit, and made an awful noise then quit. I said words, stopped, and restarted the engine. It was making a heck of a noise and idling about 3K+. I thought oh $h!+ that sounds expensive, got out, listened and thought I blew a head gasket. Well it turned out to be the PCV valve was blown out of the case when the engine turned backwards! I put it back in and the idle returned to normal! Real normal, not the 2K normal it was doing for a past few weeks! I'm thinking something that was sticking was un-stuck! Happy, Happy, Joy, Joy.

Gah! I think I'd stick to a less intensive fix...

Glad it worked out for you...you're brave...I think I would have tried a family remedy first that could be administered within the privacy of your own garage!

What fluid is used? Where does it hook up? I need step by step instructions and a supplier. Is there a vendor in this group? I bet Dr 914 has them, it looks like an item a doctor would have. Group purchase!

You are lucky! I spun my car out a while ago... Forgot to push in the clutch....spun the engine backwards, and blew out the MPS diaphragm.
