Axel,

OBD-II it and reset everything. Double check on the tranny fluid level. Flashing arrow indicates tranny ECU problem, that can be as silly as low fluid, as little as a half quart or loose connector for a sensor, etc... as Robhas noted.

As for idle re-learn, even the factory manual seems unsure. I usually turn off ALL electrical loads, I even disengage the parking brake to turn off the dash lamp, let the engine idle for 10 minutes. The manual also states that you have to drive the car for such and such miles, blah blah.

That's the beauty of electronics. Once something goes wrong, no one can figure out the problem, including the guy/gal who designed the system[8D].

I will continue this on a separate thread now that it is not related to PCV anymore.

 

Here's a pictorial how to for replacing the pcv and hoses, I don't remember if it describes the heater valve or not.

I did mine last year on my 94 dd and did it with the kit from FCP, it took me 8 hours at home with all the distractions but it was like new when finished using the kit. I was having vapor pressure at the dipstick and oil fill cap and the trap was plugged up nearly solid.

I read somewhere, maybe VS or the BB about someone frying their ECU while re-connecting a battery. If you look around you might be able to find more on it.

 

Do you mean the engine ECU or the tranny module?

 

I was trying to remember the thread for it's exact content and location, I'm looking for it now. I'm thinking it was for the tranny but I don't remember enough to pinpoint it until I find the, (a) thread. I'll keep looking.

 

Thanks Wallie. Please post your answer on the thread I have opened for my tranny problem. I wonder if the car would even move if the tranny module was fried.

Regards
Axel

 

IF your a DIYer like I am, all you really need to replace is the hoses that run under the intake (in the foam). They are extremely brittle, and if they weren't broken already, they will be when you take them out. The oil trap box is cleanable if your patient. I let mine soak in the sink with dish soap for a long while, banged it with about every object you could think of, and shook it with water in it, and repeated this for a good 3 hours. a TON of crud came out. Also in the sink was the sensor thing that plugs into the air tube by the turbo. I used a toothpick to stab at the holes until clean. I'm not sure if their is anything inside to damage or not, but I figured i was this deep so i might as well risk it. Make sure to clean the ports on your block as well. These also get clogged up, and may even be the whole problem int he first place. Hope this helped.

 

Maybe your oilpan orings, could be gunked up.
