I went back to my old tune this weekend and after driving for a few miles I threw a check engine light - this sucks!

The old tune is less agressive and the idle is lower. I used this tune succcessfully for over one year with no problems. Oh well!

One thing I did several weeks ago in an efffort to pass emmission sniffer test was to install new 02 sensors. I lenghtened the cables on the passenger side about 1 foot. I heard this is not a good thin to do, however.



I'll check out the code in a day or two.
