The DOD function on my '09 GT is really annoying. It goes to 4 cyl. mode on a level grade at low speeds or only downhill if traveling at 70 mph or above. The slightest load on the engine puts it back to 8 cylinder mode.

There have been endless discussions on eliminating DOD, but it appears that only doing so with a change in the computer will eliminate it completely. I know that if you remove the oil pressure sensor plug or power brake sensor plug, DOD will not activate.

There are plug-in devices for the OBDII slot that stops DOD, but they're fairly pricey.

Anyone here know of a simple fix?
