Thread: 2.4 Puma - Possible Injector Problem

Heya guys,


I am having a similar issue as described in this thread, with an erratic idle and a random loss of throttle response when driving. The only extra symptom I am having is that during the loss of throttle response my temperature gauge goes all the way to the top and then comes straight back to normal and then I get throttle response back??? I ran the live data on the Hawkeye Pro while driving today and when the throttle loss and temp up came on the actual temp on the ECU did not rise, it stayed on a steady 113 C. does anyone have any ideas?? Could it be the same fault as you have had and this fault is somehow causing the temp to read high??


Cheers

113 degrees is actually a very high coolant temp (that you should probably only see flogging up big hills on a hot day) - while I've never got a definitive answer, my recollection is that overheat limp mode kicks in at either 114 or 116 degrees (coolant temp not cylinder head temp). The temp guage is also normalised between around 75 degrees and 115 degrees (give or take) and will then head north rapidly.

My first blush reading is that you have a genuine over heating issue - have you checked your coolant levels lately?

Edit: Also, I think there's a main relay issue that might affect the temp guage too but can't remember the details off hand.
