Why does my 2003 Electra Glide (EFI) run like crap when it gets hot. Runs fine prior too..., after 20-30 it hesitate and runs like the plugs are fouled. I have replaced the fuel hoses, new plug and wires. Any thoughts?

 

Head temp sensor maybe? CKP sensor?

 

I had an 04 sportster that did that. It was the crank position sensor. You can test it by putting cold water on it as its running. If it improves there is the problem.

 

Does it have a tune or is it stock?
