Here is a tough one to figure out

2011 Bd intercooled pro rmk. Runs perfect! Starts great when warm or when sitting in a heated shop. Starts great when cold -22 c yesterday. Here is where the problem starts. It won't idle when it is cold and of course reverse won't work because it quits. Keep it running until coolant temp is 80 still won't idle. Let it die unplug the fuel pump, it will fire right up and run unitl it's out of fuel. Plug the pump back in and it idles perfect and will for the rest of the day. It started doing this about a year ago but was not very bad. Had to keep it running when cold for about 20 sec then it would idle. Has slowly been getting worse. In a warm shop it will start and sit there idling.

My thoughts are that it one of a few things that it could be.
1. Polaris intake air temp sensor
2. Boondocke intakle air temp sensor
3. fuel pump(current draw pulling voltage down to ECU)

Thoughts?

My bet would be the TPS is off. Have it checked first.

How many miles on your reeds? mine wouldn't idle either and they were shot on the bottom row. This doesnt explain all the issues, but if you have 1500 miles on them boosted, they may be bad.
