    International 9400 with c15 mbn. Wierd problem is occuring, If im cruising and hold the throttle pedal steady it will kind of decel and accel slightly on its own. Sometimes if i push the pedal just a little it seems like it really kicks in like another cylinder is kicking in.

    Could be your throttle position sensor. Would have to hook up to computer to check it
