2004.5 Sportsman 700EFI running lean
Hello. I am new to this forum and I am looking for help. I have a 2004.5 Polaris Sportsman 700efi that is running very lean and backfires at low throttle and does not like to idle once warmed up. Fuel pressure is at 38-40psi and I am getting code 51 and 52. I have tested the Tps using the Polaris tester and also replaced the t-map connector. as far as I can tell both intake boots are fine. ( tested them by spraying carb cleaner on theem while it is running) I am at a los with this thing. Does anyone know what I should check next? Thanks in advance.

Carguy. Im havtng similar problems with the same machine but I think mine is running rich. .I ordered the T Bap connector today. Not saying you did just a reminder you don't want to use carb cleaner inside your throttle body or on sensors. I did use CRC brand throttle body cleaner and MAF sensor cleaner it helped brought the idle back and ran fine now I have other problems.
