****Its the CM that is mounted on the heat sink right at the top passenger side of the engine.( Aluminum heat sink...cant miss it..right at the top. the icm is attached to it)

Buy a new one($74), and buy the silver heat paste at radio shack ($14).
take the whole assamble ( heat sink and CM mod) off the braket its mounted to because this is the cause of the problem. The bracket is mount to the engin and IT conducting heat back up from the engine causes all the problems.

After replacing the CM and applying the new heat paste, tye wrap the entire thing on the cables coming from the gas peddle to the top of the engine that are right in front of it , in such a manner that the air flow from the radiator will run down the length of the heat sink fins.

Simply tye wrapping will work fine and there is just enough length on the wires to the CM to allow it to reach.

This WILL finally solve this vexing problem. Simply put it is a design fault.
The CM is heat sensitive and is mounted to a heat sink. the problem is the bracket that ITS mounted to is hotter than hades and conducts the heat back into the CM via the heat sink.....crazy but do what I suggest and THAT problem is fixed...
