My '98 Ford Crown Vic has three components that need replacing:
* oil-pressure-sender unit
* idle air-control valve
* the number 5 coil pack
I've replaced the pressure sensor on my old Olds Regency...messy but easy; I assume it won't be too much more trouble for the Crown Vic
I've never replaced the IAC valve or coil packs (I'm a fearless do-it-yourselfer...brakes, p-s pumps, rear springs & shocks, etc, but I don't even know what the IAC or coil packs look like or where they're located). How difficult is it for someone with no prior knowledge to replace these? The dealer wants ~$500...no way.
