So to begin I noticed my oil pressure sender unit leaking really bad so I changed it. Then along that repair I noticed my battery to engine cable was in really bad shape. So I got a new cable from Napa and changed it out. Now when I start my car it has a horrible hesitation through slower speeds but runs fine once it gets to about 25 mph. It also idles pretty rough now. Before I did the swap it was running great. Any ideas why this happened or if changing the cable restarted or messed with any of the electronics? Thanks for any help.
