    Hi, I have a '05 FXST with a 88 engine with only 1800 miles on it. The check engine light just started to come on. It has come on and then goes off a few times now. It runs fine otherwise. When I turn the ignition switch and the run switch on, the engine light comes on and the blinkers flash 3 or 4 times. What is the problem? Thanks! Kevin

    Could be the O2 sensors. They are connected at the exhuast pipe and mannifold on the engine (if Im not mistaken).
