SOURCE: 6.0 powerstroke noise

Not the turbo on it's last legs. Check the hoses that come off of your turbo that go into the intake. Fords are famous for the hose clamps that hold the hoses in place breaking or coming loose and the woosh sound you hear is the compressed air being forced out of the hose somewhere when the turbo spools up. When this occurs you probably don't have quite the pulling torque you should. You will notice quite a drop in performance. Check the hoses or rubber boot connections from your turbo.

SOURCE: My 2000 taurus keeps showing

I had the same problem on my '02 Taurus, 3.0, V-6, 24 Valve engine. I replaced the plugs and plug wires which helped the problem but did not cure it. I then replaced the ignition coil (Motorcraft part # DG-485) which solved the problem. Has been running great since then...

SOURCE: Getting a code of misfire on cylinder 2, Bank 1 and lean code

Higher compression usually only happens when extra oil is introduced in to the cylinder.Your rings seem good due to the good compression .If there is a worn valve guide in that cylinder this would allow oil to seep into the cylinder .Also allowing for extra rocker arm movement which could be your chirping noise and cause a rough idle.The lean code sounds like something different like the is still a vacuum leak.It sounds like you know cars well ! I hope this helps

2006 ford five hundred - engine code P0301. When first starts, no issues, but then idle gets rough and car loses power. Miles from home with no tools but willing to do whatever.


P0301 cylinder # 1 misfire !
P030x - Cylinder x Misfire Detected Description: NOTE: x represents cylinder number 1 through 9.
The misfire detection monitor is designed to monitor engine misfire and identify the specific cylinder in which the misfire has occurred. Misfire is defined as lack of combustion in a cylinder due to absence of spark, poor fuel metering, poor compression, or any other cause. Possible Causes:
  • Ignition system
  • Fuel injectors
  • Running out of fuel
  • EVAP canister purge valve
  • Fuel pressure
  • Evaporative emission system
  • EGR system
  • Base engine
Diagnostic Aids: The malfunction indicator lamp (MIL) blinks once per second when a misfire severe enough to cause catalyst damage is detected. If the MIL is on steady state due to a misfire, this indicates the threshold for emissions was exceeded and caused the vehicle to fail an inspection and maintenance tailpipe test. Application Key On Engine Off Key On Engine Running Continuous Memory All - - GO to Pinpoint Test HD . Could be an ignition coil !An to replace it the intake manifold has to come off !

check for ghost codes, the light does not need to be on to have codes stored. I would also check your vacuum lines as these can have strange impacts on a idle. check you pcv valve to make sure it is working proper

The first you should be taking when getting error code should be to replace the faulty spark plugs and their respective wiring. Also check for faulty distributor and ignition coil. If everything till now is fine then and only then go for cleaning throttle body.

Random misfire


Intake manifold gasket or cracked intake manifold will cause a variety of problems including rough idle and random misfire. You can try spraying a little carb cleaner at various points around the intake manifold while the engine is idling and see if the RPMs pick up at any point. This would indicate that it is drawing air in someplace where it shouldn't. The slow acceleration is probably because the computer has set itself all out of wack and is trying to compensate, that's why you get codes like O2 sensor when it really isn't bad, it's just raw gas getting to it.

97 Chrysler 2.5L runs bad when warm stalls and knocks no MIL


It sounds like you did not change those intake manifold gaskets and they are not completely sealing the intake and causing a vacuum leak and the MAP sensor will read high in voltage and cause the bad idle.

spray carb cleaner on the intake manifold near cylinder 1... common problem is the intake manifold gasket leaks vacuum causing a misfire...the not starting could be due to a faulty crank sensor
