HELLO WHO EVER MAY BE OUT THERE, WE HAVE A FORD ESCORT THAT WILL RUN FINE UNTIL UP TO FULL OPERATING TEMP AND WILL THEN START TO HAVE A BIG DIP IN POWER AND A PRELONGED FLAT SPOT IF THE THROTTLE IS HELD RIGHT DOWN, IF YOU THEN LET THE THROTTLE OF AND REAPPLY LIGHTLY THE CAR WILL REV OUT FULLY, AND NO POWER LOSS OR SPLUTTERING OCCURS (WILL SOME TIMES POP BACK IN THE INLET AND SMELLS LEAN WHEN BEING FORCED TO RUN UNDER LOAD) VEHICLE HAS HAD A NEW TPS SENSOR FITTED BY ANOTHER WORKSHOP (STILL SAME) WE HAVE CHECKED KEY ON ENGINE RUNNING FAULT CODES AND FOUND NO FAULTS. FUEL PRESSURE STAYS AT 3 BAR-4 BAR EVEN WHEN THROTTLE HELD DOWN AND ENGINE SPLUTTERING. FOUND SOME WET AROUND LEAKY BATTERY TRAY ABOVE ECU SO REMOVED ECU AND CHECKED BUT DID NOT SEEM TO HAVE GOT ANY WATER INSIDE UNIT. WITH FUEL PRESSURE BEING 3 BAR COULD I STILL HAVE A FUEL VOLUME (FLOW PROBLEM) AS HAVE BYPASSED FUEL FILTER BUT FAULT IS STILL THERE. ANY BODY WITH ANY SUGESTIONS WOULD BE GLADLY RECIVED.
