I know that this seems ridiculous, but do you have the correct spark plugs in it? A too cold range of plugs could cause this problem.

The ECU (electronic control unit) is the "brain" that receives info from all the engine sensors, determines how much fuel should be injected and then sends a signal to the injector.
The temp needle should be moving at least 25% up the gauge after driving around for 10 minutes. If it doesn't, I would replace the thermostat.
I have replaced the coils, the injectors, switched to a hotter plug, checked the computer module, replaced the temp sensor. Still can't get the left side to run without fouling which causes missing and loss of power. Does anyone have additional suggestions as my JD mechanics has given up on this older rig. I love the machine and wish to keep it going. The service techs contacted the main corporate service center and they said that it was too old for them to put energy into helping them solve my problem. They actually refrained from charging me for the true total of hours that they put into trying to fix it for me. They did get it running better by discovering a problem with a secondary wiring harness that attached to the temperature sensor. It ran reasonably well for the Summer, but in the cool temp it is back to erratic running. What now?
Replying to an old subject....Unfortunately the fouling problem is an engineering issue. There is no cure for it.I have replaced the coils, the injectors, switched to a hotter plug, checked the computer module, replaced the temp sensor.
