Issue is with a RHD Australian 12/2000 Ford Explorer XLT 4.0L SOHC
On a really hot day (over 40C) truck goes into Limp Home Mode (LHM) and will not drive faster than 15Kph. It is OK on other days! When it is running normally it drives and sounds fantastic having installed new timing chains, guides, valves etc. a year ago.
There are no fault codes showing with my OBDII scanner and the fuel trim values look reasonable both when it is running normally and when in LHM. The fuel pressure seems OK.
I have cleaned the Throttle Body, Air Flow Sensor and changed the Ignition Coil Pack (supplies all six spark plugs). Truck has new HT Leads.
When it was in LHM, I used a whole can of electronic freezer on the engine computer (PCM) after exposing the printed circuit board by drilling out the pop rivets and removing the PCM’s top cover, which made no difference!
I have yet to change the spark plugs but they were OK a year ago.
Any ideas much appreciated.
