2002 ford taurus almost seems like its missing when driving,idle.

I've already changed the coil pack(recentely), wires and plugs(within a year), pcv valve, and there is oil going into the plenum(intake) and none of this has helped. I'm so frusterated. PLEASE HELP!

You will need to do a running compression test. Sounds like you have ring issues. Too much blow by causing excessive crankcase pressure. Also pull the dipstick. Put your finger over the hole with the engine running. It should be pretty nuetral in pressure. If you have vacuum you have an intake leak. If it blows pressure you have an engine issue.

    Parts do wear out. All you can do is test to know whats really happening.Process of elimination is to first test the integrity of the engine.

2002 Taurus 24v Duratec getting 301 and 316 codes. Misfiring bad while idling at a light or drive thru. Any ideas ?

Ok the P0301 code means that your engine is misfiring on the first #1 cylinder so that is good you know where it is coming from. The P0316 Code means that your engine is misfiring in the first 1000 revolutions of the engine starting. What i would suggest you do is change the plug and wire on cylinder #1. If this doesn't solve your problem then you can go to your coil packs and change that. If that still doesn't solve your problem then it may get difficult leading to an injector. But i am almost positive that it is going to be no more then a plug wire or coil pack!

Have you checked your camshaft sensor? It's possible that the vane on the Synchronizer is misaligned.

2002 Ford Tarus intermittant missing cyl #3 after tuneup

I would remove one plug at a time, plug it back in wire and lay on top of engine block. Have some one crank and look for spark. Do this for each plug. If 1 is missing. You have bad wire. If two sparks are missing, then you have bad coil pack, if 3 is missing, you have two bad packs or bad module, if all cylinders are missing, then module or cranks sensor is faulty. Dont forge to change those plug wires just as often as plugs. They may look good still, but they get weak

Check your idle air valve, maybe your air filter needs to be changed. EGR valve may need to be checked at as well.
