the other day i noticed when i was stopping at a light my truck started to stumble so i stopped at the light and while at idle the truck was just shaking and stumbling just like it was gonna stallso the light turns green and i accelerate and the stumble is gone. its happened a few times in the past week or so. i have no codes. any ideas. i also figured ide add a few pics of my atv. i just added the tires and wheels and the snorkels. what do ya all think

Suggestions:

1. buy good gas, no mom and pop stores
2. tune up: plugs, wires, cap and rotor, air filter, PCV, o2 sensors, maybe even a new coil
3. Replace IAC

my buddy just bought those same tires for his vinson 500. there pretty badazz. what size are they?

 

there 27-9-14 front and 27-11-14 rear. on 14"itp ss 108's they are bad a$$ tires. i sunk my atv a few weeks back and decided enough was enough so ibought the bigger tires and added the2" snorkels. the snorks reallymade alot of power.and i always buy my gas from hess. its not a small gas chain. and they dont do business with the middle east which is a great plus. my tune up was done a year ago. and i cant see myself needing another one already. ill change the coil and see what that gets me. im assuming thats factory.

 

I've had a stumble for since i can remember on startup. and can sometimes on idle. I did everything suggested and still have it except for the o2's. I just learned to live with it lol. Plus it adds a hissing sound on cold startup too. which is a + for the open air cleaner

 

i have this same problem if you have firgured out what it is ?

 

i havent even looked at it. weather has been kinda crappy. im going to do a tune up and get a new coil. and run some injector cleaner as i usually run super every so often but with the prices i havent. so ill run some seafoam through it and see how it does.
