Hi all - new here, and this be my second post (arr?) - I just purchased a 1999 Limited with 102,000 miles - its in great shape (aside from this) and was a great deal (provided this issue does'nt end up clearing out my bank account).
First problems: After I left the lot it "hesitated" badly - about 1.5 miles down the road the CEL came on. :cry2: I returned to the dealer and they pulled the code (I wish I wrote it down) and they told me that it was most likely due to the work the detail department did (the completely cleaned the engine compartment) - they cleared the code, checked other things and it seemed to run better (but never "right") - having dealt with CEL/ECU/OBDII I knew I needed to wait a full "cycle" for the ECU to "relearn" and accepted that it would not feel right - after 1 day the CEL came back on, this time a P0171 (wrote it down this time) - the mechanic at the dealer told me this code was different from the first one and he proceeded to check vacuum lines, look for leaks, etc. He reset the CEL and told me to bring it back if it happened again.
THE NEXT DAY it happened again (and during this whole time it was never running right); The code is the same and after reading through the forums I'm going to try to clean the MAF before taking it back to the dealer. I have the AutoEnginuity Scan Tool product so I can pull all sorts of information in real time from the ECU - if anyone can think of something else I can look at (temp, psi, load, etc...) let me know - I do plan on getting a Hayes/Chilton book but until I do I'm going to rely on the input of my new friends - hopefully!
Addendum: I read somewhere about "soft" brakes being a sign of a vacuum leak - the brakes ARE somewhat soft and "sticky" if that makes any sense...
Thanks for whatever you can offer! I have been a member of Pontiac, Chevy and VW forums in the past and I am excited to be with a new group of people!
