My F-12x is running terrible after 4000RPM. I also have fouond that when the switch is off and clip is pulled I have a clicking soound coming from what appears to be a box right under the fuse box. I pulled the fuse for the INJ ( assume that is the injector module ) and the clicking stopped. Could this be an indicator that somethign is wrong with the with injection control module? Why is it clicking? the clicking does not stop even after hours of being off. It ONLY stops when you put the clip back in, but seconds after pulling the clip off it starts again.
