So the last couple times my 900 has been bogging at low end, it's blinking the check engine light 5 times, last year i had replaced the exhaust temp sensor because it was blinking 5 times. After i had replaced it about 2 days later it started blinking again when i started it up. So i just ran it like that untill this year and ran fine, couple weeks ago i went riding for a few days. First day the sled ran awesome, but on my way back to my truck it started to bogg like it was starving fuel on the low end, reset my boondockers box back to 0 for everything and still doing it. Next day took the sled out to try to figure out the problem, ran fine for a while but after it was warmed up and stuff it started backfiring and bogging at low end really bad so i just parked it. Did notice the little check engine light on the tach blinking here and there also. Once i'd pin the throttle to get past the bogg the sled would run like hell.....any thoughts on where to start or what to look at? Plugs are good and light brownish color,I checked my intake boots and they look fine...maybe TPS? Thanks in advance for any help!

is your boondockers box grounded to the recoil housing ONLY, or even at all..
the box ground will cause this..happen to me 2x...

sounds like classic tp issues. i was fighting simmilar issues i would check the connections on the pipe temp sensor for the 5 flashes and check the tp sensor connections for corrosion and check the wires for possible breakage right where the wires are crimped to the wire terminal they will break there and make intermittent contact. it can also be a faulty tp sensor you need to test it with an analog meter check the sweep to make sure it is smooth from closed to open throttle from .93 v closed to 4+ volts at wide open throttle.
