OK same problem crept up again with this d*mned car. The car sat a whole week with the avg temp at 27 degrees, this time my brother made the ECM believe that it was warmed up to 151 degrees and the car started (the first time this happened in November the car was already warm). What could possibly be causing this. Using a SNAP ON scanner, code 55 comes up which means everything is normal, but obviously everything is not normal. Does anyone have any ideas? Does the fact that this time the car was cold and last time the car was warm rule out the cold idle sensor?

TIA
