got my bone stock 88 Sam home last night, ran great when I left Rods place, ran horrible as i got off the freeway an hour later. later that night I went out and took it for a sppin and it was running fine again. this morning it was running bad again, no cruise action, idles like new, wide open throttle is fine just wont cruise down the road. I wood love to toss this for a less electronicaly loaded card, any suggestions ?
