My 2000 Lincoln LS V8 issues

You most likely have a transmission that has seen it's better days, very common issue in these models.

You need to check for a vacuum leak and throttle housing. Also if possible scan for codes you may also have a coil issue

V6 or V8

I have a 2004 V8 & all the manuals for 04

No one will provide you what you need
& very few people but me, even answer
LS questions

Only made for 7 years & too high tech

What issues do you have?

is your temperature gauge drop closer to "C" when the vehicle is moving at high speeds?? If so, this may be a stuck open thermostat, or missing thermostat. Replace to prevent this issue. Hopefully this helpd!!

Symptoms indicate a dirty throttle and idle air controller interior. Remove the air ducting between the air cleaner and the throttle. Use a cloth and WD40 spray and clean the throttle interior and throttle plate. Rotate the plate and continue cleaning further in. When all clean reinstate the ducting and test.

Clean MAF--CRC MAF Cleaner
Clean Throttle plate--CRC Throttle Body Cleaner

Forget the four coils. That is a common problem,but I would question 4 failing.
The ABS ,Parking Brake,Speedo Etc,where nothing to worry about,you were loosing power, when it went to fail safe,so they came up.

ETC -is Electronic Throttle Control, your problem? Maybe
You will need to have a scanner put on it's,daignostic connector under the dash,to check for codes. Them only a trained technician can follow a chart or test proceedure to properly repair.
I have a 2004 LS,one of Ford most high tech and complicated vehicles.
Conclusion: only a professional can repair you car.
I would start with a local shop. If money you have money to throw away,go to a dealer.
Most likely have to wave to it on a flat bed carrier. Don't flat tow it.

PO-113 Intake Air Temperature (IAT) Sensor 1 Circuit High Output

P-2104 Throttle Actuator Control Sysrem-Forced Idle

P-2111 Throttle Actuator Control System -Stuck Open

Without the vehicle,I won't tell you ,that you need to replace anything

The Throttle Actuator, is similar to Toyotas issuses with the gas peddle

To Diagnose what appears to be multipule issues,you need to check out the gas peddle sensors,the throttle body and the MAF Sensor,which has the AIT ,air intake sensor,part of it.

You could carefully remove the MAF and spray only with -CRC MAF Cleaner. Make sure the throttle plate moves relatively free. If you spray it,again Penzoil Throttle Body Spray or similar product

Most likely,your going to need a professional scan tool and some experience,to work out your problems.

try tapping the end of the key gently with a small hammer while trying to turn it this happens alot on Ford Escape and Focus

you may have oil leaking on exhaust.
