Would that throw a code 15?

Nope, but thought that code disappeared when he changed the TPS?!?!

agree, you can pull the fuel rail out of the intercooler zip tie the injectors into the rail and turn the key on. there should not be any fuel coming out of the injectors.
could be a stock one but more common that its a secondary.. julio

Yesterday we found a broken or near broken wire going from the MCX box to the TPS. Repaired the wire and all seemed good. Going up the trail the sled started acting up again and threw the code 15. Once the sled is warmed up fully it seems crap out, stone cold it runs fine. Ideas????
