Question about 2002 Ford Taurus

1 Answer

Having more codes after I thought I fixed the missfire

I had a miss fire on cylinder one. I have replaced the fuel injector, spark plug, and wires for my 02 ford Taurus and have changed out the EGR valve/sensor ( I got a code for this after I changed the injector). I thought I had the problem solved but now I am getting a P0172 Code Adaptive fuel to rich and the other misfire code has come back. What should I do to fix these? Is it possible that when I took the upper intake manifold off the second time I did not line up the gaskets and would this cause the problem? I have also visually inspected the vacuum lines and found no cracks in them but could this still be the cause?

Some time when you take off the intake manifold you have to replace the upper gasket and i would take it apart again to make sure you have the gasket line up try these websites www.autozone.com and www.alldatadiycom and the other one is www.taurusclub.com

Missfire on cylinder 8 on bmw 545


move the ignition coil to another cylinder and see if the miss fire moves. If so replace that ignition coil. If the miss fire stays on that cylinder it is more likely the fuel injector. Was their carbon on the spark plugs when you removed them? This is indicative that the fuel injector is gummed up.

You've done a great job of trouble shooting thus far. I would certainly suspect the injector after all of that. But, I didn't see anything about you replacing the spark plug itself. I would try that first as a crack in the insulator (even hairline) will cause mis-fires. If the spark plug doesn't fix the mis-fire, it cold be caused by a bad fuel injector, bad signal (like a loose harness or bad wire) to the fuel injector, or a leak or valve issue on that cylinder.

  • A missfire could be alot of things. If its "pulling a code" then its probably not spark plugs or plug wires. Most of the time it will be a coil or crankshaft/camshaft position sensor. If its a little miss then it could be a dirty injector where only some fuel is getting through. If the injector plugs are easy to access i would unplug #3 while its running. If there is no change, its probably a spark issue and would bring your coil in to autozone or anywhere that can test it. If its good, get the crank/camshaft sensor tested. If the idle gets a little rougher when you unplug #3, it could be a plugged injector

Cylinder number one stops firing, and black smoke comes out of the exhaust. I replaced the coil pack and spark plugs. when i unplug battery and reset the faults, it drives fine for a couple days. what...


honestly it sounds like you have a bad computer. there is a constant 12 volts going to each fuel injector and the computer momentarily grounds each fuel injector to activate, the black smoke is from too much gasoline and the missfire is probably from the injector either hanging open or being held open electricaly. next time it starts to missfire on number 1 cylinder try taking a stethiscope or long screw driver and put it on #1 fuel injector with the engine running and see if you hear a clicking sound. If not try unplugging the #1 Fuel injector. this won't fix the missfire but you can see if the black smoke clears up. if the smoke doesn't clear up with the injector unplugged and you are sure its # 1 cylinder thats missing, replace #1 fuel injector.

Hesating, Though I had bad gas, I was told that my first piston is miss fireing. How can I fix it?


You will first need to determine what is causing cylinder number one to missfire. Could be a clogged fuel injector, bad ignition wire, bad spark plug, burnt/bent/stuck valve, cracked cylinder head, bent push rod, collapsed lifter, flat cam shaft. I could keep going, point being there is no easy fix unless we start eliminating possible causes. You having bad gas I would lean more towards the injector or the spark plug.

More codes after fixing I thought I fixed the missfire


Have you looked into your MAF Sensor? Also, did you have the codes cleared after you did the work? If you don't clear the codes, they'll come back. You have to have the codes cleared with a diagnostic machine (I don't know if an OBD-II reader has this capability). If you didn't have them reset before, try doing it now and see if they come back.
