Your posts are a ******************** to read...run on, incoherent, lack of punctuation, etc. This isn't IM. If people can understand what you are trying to say without needing a decoder you will receive some great info. Just a suggestion.

Okay, I took it over to a porsche dealer and they ran a diagnostic and couldn't find anything creating the idle problem due a computer/cel issue. They were fairly sure that the idle problem was due to the throttle body. They wanted to replace the throttle body for $328 in addition to the $100 I had already spent for the 1 hour diagnostic. I opted to take it home and clean it myself. A quick trip to autozone, I purchased STP throttle body and air intake cleaner for about $3. After cleaning, the idle problem is NONEXISTENT!

The throttle body was extremely dirty, and to all of you with MAF problems due to not replacing the air filter regularly or due to an aftermarket oil type filter that was maybe over-oiled, you may also have the same exact problem as me if you have idle fluctuations.

Thanks for everyone's help in helping me diagnos my problem here. All is good now, but I'll be in touch when the next issue arrises.
