I have a 97 intrepid with a 3.3l. It blew the engine control fuse located in the power distribution center fuse box. replaced the crank sensor and coil pack and added a 30A fuse to get it to run. 3 weeks later , it blows again while idling in the driveway. shake some wire harnesses, disconnect and reconnect sensors, replace 30A fuse and it starts again. Anybody got any ideas what may be causing the fuse to fail intermittently?? thanks
