Dreaded intercooler failure??
I thought I would be lucky and avoid this, but....
Drove to Hamilton ON this past weekend. About an hour out, going 75 mph with temperature in the 70s, I pushed the pedal to the floor and it dropped two gears to 5500 rpm and nothing else. A couple miles later I tried it again...same thing. Then again, and it responded like normal with lots of power.
Over the course of the weekend I discovered it would intermittently run normally and then run with no power. After a while I could detect when it cut out (the car seemed to surge ahead a little as the load of the supercharger went away) and then when it cut back in a few minutes later (the car shuddered and slowed slightly as the s/c re-engaged).
Sound like the intercooler / intake temp sensor / aux water pump for intercooler problem many have encountered???
Interesting thing is that the ambient temperature was consistently in the 60-70s and the water temperature ranged from a needle's width below to a needle's width above the center line. No indication the vehicle was running hot.
