[QUOTE="Greg Bosin, post: 1014494, member: 55355"] I blew 2 more fuses back to back after a trouble free day. This was after I noticed a surging idle and stepping on the throttle hard at a stop light, replaced the fuse then it blew again when I pressed the throttle to get on the road. I replaced that one and got back to my job. After work I ohmed out the PCM diode and it seemed normal, 1700 ohms forward biased and open in reverse biased as it should be. I pulled the PCM relay shook it and plugged it back in. I haven't had any trouble for a couple days and the idle is fine. I dunno but I carry a lot of 25 amp fuses now. [/QUOTE]
