Hi folks. Iam relative new in RZR world, but i can learn fast.

Iam having this problem, when my RZR is cold (95 to 185 degrees) i have poor throttle response and pops/backfires, after full warm (190 to 205 degrees) it runs better but not at all, at low rpms (about at 20 to 25 mph) pops again and feels like poor power when throttle from cero. The spark plugs are OK. i clean the gas tank and the TMAP sensor, the harness is new from dealer, no clogged fuel tank vent. The pops ups can hear if i start up in park and throttle a little bit, when cold is worse.

Need some help. Please.
