motor surging

[BobP]

There's a procedure in Yamaha service maual to test them, I only intend to clean them.

Then if the motor idles cold same way, into dealer it goes - still under warranty. I'll have to pay for hauling it there though.

Guys,

As it turns out i had two fuel injectors that went bad. The other 4 were serviced and 2000 bucks later that motor purrrrrrrrrrrs once again. I only had 197 hours on the motor so i dont know why they went bad. I was told it wasnt the gas.

clean the sensor tips only with t-body cleaner or ring free

to test them you need the break out harness

also clean that barbel out also
