If your car has had the cooling TSB done, look for an extra grounding strap coming from the black box’s wiring harness behind the ECU. A lot of people fail to hook this up when they swap out the computer. Don't confuse it for the black and yellow wire that has a spade connector, which is a constant 12v wire.
