I replaced the FCA yesterday trying to fix the eratic idle at start up when cold. Well, that fioxed it, but now it is hard to start. The temp here this morning was 32, and had to crack it 3 times( crank go dead), but then when it cranked it was fine. No cranking issues before now. Any ideas? Truck has 158 on the clock, dont know what has been done before i owned it.
