Any ideas about this Cold start issue? 2013 ST

[RangerRick]

Any ideas why the last 2 times I start my 2013 Spyder ST, it fires up then stumbles and dies starts back up and does it again. If i give it throttle it revs up fine then will idle, kind of stumbling briefly then is ok, when warm starts and idles fine.

Fuel issue? Check fuel filter or worse yet, the fuel pump. Not sure how the fuel pump functions on a 13, but let it sit for 10/15 seconds before you hit start after you've turned on the key. How old is your fuel?

Sounds like a bad O2 sensor to me.

thanks for the reply's fuel is good runs great does not act like bad/fuel starvation. Wow $254.00 for 02 sensors, there are 2. won't replace at that price without knowing for sure that's the issue. might try a new fuel filter though

WOW $254! I'd start looking here, good luck.

Check the air filter too, unfortunately also the purge valve can cause stalls if you topped off (edge overfill)tank & it sloshed around.:barf: double check if in N
