OK, I bought the right stuff, located IAT low and slightly forward of air Cleaner in CAI space. Plugged everything in and (this is where i need expert help- but since You guys are free, I'm coming to you first). First thing after start up was that cooling fans came on with cold engine IAT indicted 91Deg. Let warm up and drove a short distance- IAT krept up and I expected it to be more sensitive than OE but doesn't seem to be. Shut off and cooled for 1/2 hour. Started and drove, first time I ever had a miss at 3600 RPM then saw Engine light from hell!!!! Drove another short distance,seemed to run ok then stopped and converted back to OE. Engine light from hell stayed on until I did battery disconnect. This is wher you guys chime in- What's up?
