1999 Libcoln Cartier issues. Sign In

I own a 1999 Lincoln Town Car, 4.6 liter V8. The problem started a couple of months after I bought the car. It ran great. I bought it with a hundred and ninety thousand miles on it. Since then I've put a few thousand on it. At first I noticed the gas pedal would lose compression. And gradually that turned into the car actually shutting off. My check engine light was on and it said that all my O2 sensors were bad. So I replaced all of my O2 sensors expecting the car to run properly. I'm driving around town with my AC on and then my car loses compression in the gas pedal. I floor the gas pedal try to give it some gas and it just died then shuts off completely and I have to pull over to the side of the road. My car stays off for about 10 minutes and I started back up and it goes. I thought maybe I ran out of gas because my sensor is bad so I put gas in my car. I'm driving again and I get about 10 miles and I lose compression in my gas pedal again and the car completely dies in a parking lot. I let it sit for an hour and try to go back and start the car but it felt like it wasn't wanting to turn over. So the car sits in the parking lot overnight and I start it up and drive it home just fine. I drive it up to work every day, which I only live a few miles away. It drives amazing for short distances. But if I drive it anymore than 10 miles the car just seems to completely shut off. I thought maybe it was my coolant so I replaced my hose and put new coolant in it. I can't tell what the issue could be or if the engine is overheating. I thought maybe it was a fuel filter or fuel pump.

There is an oil leak on my engine and I can't figure out where it's from. It's leaking and the belt is catching it and seeing it all over my engine. So of course my engine has about a quart of oil strung out all across it. I can't figure out if the two issues are related or where to even start.

OK, first off, the computer did not tell you that all the 0/2s were bad. It merely observed a specific situation that needs to be further diagnosed to determine the cause. None of the codes state anything specific is bad. They just give you a starting point.

I have no idea what you mean by the gas pedal loses compression.

Start out by posting the exact code numbers here.

I'm just stubborn and refused to pay somebody to look at my car for me. I'm not the best first mechanic in the world but I fixed numerous problems with all sorts of cars and it's a bit of a hobby of mine. So trying to pinpoint the issue exactly it's something I want to take on myself. With a little help from you guys too.

Buy compression I mean I can floor the gas pedal all the way down and I won't pick up any speed. So when I first start my car up early in the morning or go on a short car ride, my gas pedal is normal. It's sensitive. I can accelerate with an ease. . But after 15 minutes of driving the gas pedal just stops working pretty much. I'll press down on the gas pedal which should give the engine more gas but the engine isn't getting any power. So the lack of power has to be caused from a lack of oxygen or a lack of fuel to the engine. I'm just having a hard time figuring this out. Why would my car drive you to flee on short distance drives or in the morning but after 10 minutes of constant driving the entire thing shuts down. And when I go to start it sometimes it won't even turn over or sound like it's getting any fuel at all.

Again, these problems only occur after driving for an extended period of time. And ask for the codes, I don't have the sheet on hand. But I went to AutoZone and they hooked up the reader. It came back and basically said I was having trouble and my upstream and downstream oxygen sensors. It mentioned something about Bank 1 and bank 2 Upstream sensors I have failed and something about failing downstream. The scanner said the most likely cause was faulty oxygen sensors. But I'm beginning to think the oxygen sensors went out because of a bigger issue.

My check engine light is off so I can't hook anything up to get a code. I'm thinking that it is either a fuel pump or my mass air flow

EDIT

So I just tried to pull out from work where my car has been parked for eight hours. I start the car and put it in drive and I notice I'm pressing the gas pedal down and it's hardly moving then my whole car shakes and the car dies

OK, the more I read, the more I realize you are the wrong person to try to fix this.

Totally ridiculous statement.

OK, I'll say this again. That is flat out wrong and the scanner does not tell you anything is bad. You just threw away 2 perfectly good sensors. Now if you want some help, get us the code numbers.

In the meantime you probably want to have a back pressure test done on the exhaust because it is sounding like a possible plugged cat.

you said "My check engine light is off so I can't hook anything up to get a code. " this is not true. get the system scanned post all codes.
1) the bulb is not working 2) not all codes turn on the bulb.
basic tools will allow yu to test
You could do a fuel pressure test and then with KOEO observe pressure drop. ie drops Xpsi in 5 min.
Vacuum gauge engine @1500rpm does reading drop or remain the same?

If Autozone cleared the codes you may have to run it a while to reset them.

Look, I've done a lot of work on cars. If I know the issue I can almost always fix it. I took it to two mechanics and they were both scratching their heads. One mechanic told me he couldn't do anything with my car.




I've fixed timing belts, timing chains, water pumps on rotary engines. I've worked on heating and AC and I've rewired tail lights. Recently I rebuilt a transmission and replaced the head gaskets on a camero. It's just knowing what I'm looking for that sets me apart. M having a lot of trouble figuring this out. But I'm home now and I'm going to try to find the error codes.

I mentioned some BASICS to get you started. Again I will suggest
fuel pressure
vacuum
spark
compression
