Was on the feeway onramp and was at about 4000 rpm in 3rd and went ro make the change into 4th.
The instant I put the clutch in, the car RPMs dropped to idle speed and it would not allow me to put the car in gear. I could push in the clutch and move the shifter into gear, but when the clutch was released, nothing happend, just idle speed with no gear engaged - coasting on the highway now.

CEL light comes on the instant the chutch was engaged for the 3-4 shift. The engine did not rev up at any time over the 4000 that I was doing in 3rd before the shift.

Pulled over and turned off car. Turned car back on and now everything works just fine as if nothing had ever happened, except the CEL lightis still on.

Any thoughts? I don't have a code reader.

 

Nobody has heard of this? Damnit.... to the stealership I'll go then. If anything, they'll at least be able to clear the CEL

 

The only thing that's on is the cel ?

 

Yes, and the little message on the readout that says to take the car in as the "check engine warning" is on.

The car is functioning perfectly normally now. Just the CEL light.

 

Nobody can help you until you get the code read. AutoZone will read it for you no charge. Post the code, and you'll get lots of info...

 

Yeah,, so this am.. Started the car to go to work and PRESTO... CEL gone and no further issues. No idea why or how.. but I don't care anymore. If it happens again, I'll have it read and post.

Thanks anyway.

I broke in last night and fixed your car. Just the extra mile that we provide for our loyal customers.

 

I knew it had to be the magic car fairies that took care of me.

In this case.. the Vivid Fairy.

 

The code is still retained in memory.

The next time if you get a different code, you will then pull codes and read both- and have no idea which is old and which is new. (with a std obd reader)

Its great not to care. Sometimes I wish I could do that! It'd just bug me...

He'll be back.

Hmmm... even though the CEL light turned off on it's own the computer will still retain a record that it was on and the code that it threw in the beginning? Interesting. I didn't know that.

Maybe I'll stop by the local auto store this weekend and see what it was. Just for peace of mind.

I really appreciate the input guys. Thanks.

 

You might want to invest in a Durametric. It will read the codes, allow you to reset them, and more important will allow you to log data on your engine performance so that you can actually tell what your mods have done for your car.

 

"You might want to invest in a Durametric"

has to be close to the best $300 you can spend.

 

Probably a wise investment. Any direction on where to buy / cost?

 

Wow,
For all that money you'd think that a Porsche would have a more complex computer. My lowly little Subaru WRX will store the codes, just like the Porsche ECU, but if will have a time and date stamp on it. If I'm driving around with multiple stored codes, I can defnitely tell which one came from which incident.

Are you guys sure that the Porsche ECU doesn't do the same thing?

I don't know about the Porsche protocol, but on my WRX if the thing that triggered the code doesn't re-occur in the next 5 start cycles, the CEL will go off. I suspect something similar has happened here.
