Looking for some tips as to the problem...I read several threads that have helped some but none matching my problems....Just bought a 2000 Lincoln LS V-8 101,000 miles... And within the month these problems have cropped up:
Check Engine Light comes on.....
We had a noticeable mis at idle and through all speeds.....Took the car to auto zone to have the codes checked....Results: Misfire Cylinder #8, mis-communication with (CAN ??) BUS (might be PCM).......As well as some dealer codes that the tech didn't know
I replaced all plugs (none of the old ones looked fouled, and no oil in the plug chambers) and replaced the coil on cylinder #8..... That fixed the mis for the most part.... reset the engine light by dis-connecting battery... Also replaced battery
This afternoon, the check engine came back on and the "check charging system" came on and off numerous times....I notice a slight back firing in the exhaust at idle and the lights seem to brighten and dim during the backfiring...... Doesn't back fire when raising the idle
I checked with a multi-meter...The battery is 12.5 Volts (not running) 13.0 - 14.0 while running with lights on and a/c on....(Also did a alternator check with battery charger and it was good).......
I read various posts stating the PCM could be bad....Also some bad coils....The list goes on....Since I can't find a repair manual for the vehicle, I'm kind of stuck on what to test and how....
Any help would be awesome...And thanks in advance
