- 2011 Ford Explorer xlt
2011 ford explorer 3.5l. I experienced the dreaded water pump failure and local dealership replaced the engine with a brand new motor for $7500. Afterwards we went on vacation only to have the check engine light flash under heavy loads in the mountains or hard acceleration. The vehicle will continue misfire on deceleration for some time upon which it will recover itself. We took it back and there was no stored codes! So I had to recreate the condition and live with it till the engine light finally remained on. They retrieved codes for misfire on cylinder 2 and 6. Replaced coil packs $600. Weeks later upon passing another vehicle same thing. So completely fed up I removed the intake plenum myself and replaced all coil packs and plugs thinking maybe something overheated the coil packs from the original engine failure. Unfortunately today upon hard acceleration same flashing. So decelerated and kept repeating until the dang light stayed on. When this happens the vehicle stays in misfire mode for about 20 to 40 seconds. It will recover itself every time and run normal at idle. The vehicle runs great all the time unless under heavy load I lose cylinders 2 and 6 confirmed again by reading engine codes. No other codes are present. Can someone please help before I soak more money at the dealership
