cranked up the XTZ to clean it up today and it started flashing EFI everytime I cranked it up. It seemed to still run ok, but it did die once while idling. Anybody know whats going on?

Check the connection that goes into your fuel tank. It is a four wire harness with a connector that comes off of the top of your fuel tank. This goes to your sending unit, and fuel pump. Check all connectors around the throttle body. TPS, MAP, ICU etc....

Ok will check the fuel tank when i get home tonight. sorry but you will have to help me on where the other connectors are (throttle body, tps, map, icu, etc). I know a polaris machine really well but this is my first cat so real green when it comes to fixing these minor issues. I read the post on Accessing Codes and on step #3 (3. Connect the Test Plug from Test Plug/Error Code List to the diagnostic plug.), what is this? is it something i have to purchase to check the codes or did it come with prowler. thanks for the help

Number 3, 6 , and 10. The plug you are talking about is part number 0486-219 from Arctic Cat.

checked the plugs under the seat and made sure they were still plugged in all the way. Potato head, explain the jumper wire and which pins to put them in. will this allow me to check the codes? trying to avoid having to bring the bike in to dealer

Yes but you need to know what the numbers are. Post them up and someone here can tell you.

I'd have to look but it seems the plug only has 2 pins in it. I'm probably wrong maybe someone will know. But I thought the 2011 xtz gave you the code on the display. Only thing mine has done was P0625 don't know about anything else. On vince's we did the jumper wire and it worked but his is a 10

If the ECM is black/plastic, use the jumper. key off, install a jumper between the blu/red and blk pins and then turn it on. Any codes will appear on the display. AC = Active Code, SC = Stored Code. Shut key and remove the jumper wire. If not, you risk damaging the ECM

If the ECM is silver/metal, the diagnostic plug and jumper will not work as the system runs a different fuel injection / diagnostic system. If the box is silver, the codes will appear on the display ONLY if there is a problem.
Hope this helps

ok jumped the diagnostic port and it says SC 15 and AC 15 meaning its something to do with the coolant temp sensor i think. anyone know where this sensor is so that i can check it.

Coolant Temp Sensor is located on the side of the head.
It works on resistance readings depending on specific temps. I would check all related wiring and connectors. If all looks ok, replace the sensor
