Hi everyone. I'm hoping someone can help me. Recently, my wife was using the Gator and it ran out of gas. When I filled the tank back up, it started, but when you push the gas, it bogs down and dies. Then it will not start back unless you hold the gas pedal all the way down to the floor. It cranks and cranks and will finally start, but it smokes really bad and will not idle. It almost sounds like it's running on one cylinder.
After reading another forum, I changed the spark plugs, changed the oil and oil filter, and changed the air and fuel filters. This didn't help at all. Now, the Gator will start right up and idle when it's cold, but when it warms up, it goes to missing again and will not idle. To start it again, you have to hold the gas to the floor and once it starts, it misses horribly and blows smoke. It almost seems like it is flooding itself.
What I've done so far:
I added Sea Foam to the fuel thinking it might clear it up. No change.
I'm running 87 octane fuel with no Ethanol.
I've taken the air intake tube off and sprayed throttle body cleaner in the throttle body and no change.
I've disconnected the connectors on the two sensors on the front side of the throttle body and that seems to clear up the problem, but when it starts running good again, the idle will not go down. It sounds like it's running half wide-open. I'm not sure what those sensors are since the John Deere parts manual only says sensor. The only way to get it to idle down is to remove the wire connector from the pressure sensor located on the driver's side of the throttle body.
I've thought about replacing the two sensors on the front side of the throttle body, but I don't know if they're bad or not and I hate to throw down $300 for something that will not fix the problem. Is there any way to test those sensors to see if they are bad? Anyone else had this problem?
