It has a 26 fuel injected kohler and it will miss sometimes with the deck engaged and @ full throttle. If you disengage the deck it will run fine or if you back the throttle down just a tad it will not miss anymore. It seemed as though the e-brake switch was the culprit but bypassed the switch and same problem occured. any help is appreciated.

1100 hours. Air filter and plugs were both replaced before the mowing season. Unit had the miss all year, but would come and go.

Just did the fuel filter. I will order a 02 sensor and replace. It is cold here so it will be a few months before I can check it out.
