I have a 98 Lincoln Town Car Signature Series 4.6 liter....just
recently the engine has started to idle high and low when stopped...it
seems to be running to rich...I had it scanned for codes,initialy all
4 oxygen sensors were reported to have failed as well as a
transmission code.Since something up stream has caused these codes,a
further scan indicated that 4 coil packs were triggered as bad so I
replaced all coil packs and spark plugs ( ford parts )....rough idle
still exists!!!....I am now being told that the engine computer needs
to be replaced ( yikes )...I have also been told that a replacement
ECU must be flashed to sync engine and pair of chipped ignition
keys.....How far must I go....what about idle control valve....mass
flow sensor....does anyone know the flash routine...any advice would
be appreciated......thank you.

I'd eliminate the often problem nickle/dimers first.

Does it make like a coughing sound when you turn it on in the morn?
If so, it's likely idle air control. Some info:

The MAF is not too difficult to check:
