Look around our website at http://www.townsendimports.com/ Try monitoring the 02 sensor's output voltage. Look under tune up and the cold start page for info on that. Make sure the ELCD valve for the charcoal canister is working. It may not set a code for it, but I have found a lot of them setting mixture codes because the computer tells the valve to work and the electrics of the valve say they are working, but the mechanical part of the valve doesn't respond. Result is a vacuum leak to the fuel tank. If the tank's cap is bad, the car runs real lean and sets the code. I'll bet from the description you give the car has a mixture code and it is coming from either an vacuum leak or the 02 sensor. Fix the mixture and the light will go out, no need for ISAT to reset it. Good Luck, Ywan Mason
