Hi, P0316 code means that the PCM has detected a misfire in the first 1000 engine revolutions, upon start-up (to light of a miss to set a cylinder code) The most common thing on these engines are the COP (coil on plug) ignition coil packs which have a high failure rate!!! To properly diagnose this type of misfire you will need a professional type scan tool eg; Snap-on Modis,solus etc. (not a code reader) and on the ford you need to go into mode 6 data so you can actually see # of misfire counts to get an accurate diagnosis!!! If it was a airbag code it would be a (B****) series code and the airbag lamp would be on or flashing!


Likely Cause of P0316 - Misfire Occurred in the First 1,000 Engine Revolutions

  • Damaged crankshaft position (CKP) sensor
  • Ignition system
  • Fuel injectors
  • Running out of fuel
  • Fuel quality
  • Base engine
  • Damaged powertrain control module (PCM)

Po316 y po303 en Ford tAurud 2003


Cylinder # 3 has a misfire...#1) Defective coil on plug or the spark plug itself...#2) Contaminated fuel injector...See drawings below...The coil pack is the smaller of the two and sits to the rear of engine it is the most probable cause...Although the spark plug or the ignition wire (connection between plug and coil pack) could be at fault...so, before you invest in a new coil pack...Remove from both ends the wire from #3 and switch it with #2...if the fault code changes to p0302 that wire is bad...next Install a new set of plugs....Fault still present? replace the coil pack.....Unless recently changed new plugs and wires are a plus even if fault remains...saailer

Code P0351 what does it mean


the code means "ignition coil A / primary circuit malfunction". It usually leads to a car misfiring or running rough. The coil on plug (cop) ignition system has a short or open circuit. The last number of the code tells you which coil wire is malfunctioning. In your case it is coil number 1, which should be the number 1 cylinder. These coils take the place of spark plug wires. there are 2 wires coming off of these coils. One goes to the battery, the other the cars PCM. Check that the connection is good on the spark plug, if that doesn't fix it, then check the wires for a break in the wires. It could also mean that the coil (cop) is no good and will have to be replaced. These coils (cop) are all attached to your spark plugs, so they are easy to find. Good luck.

We have a 2001 ford windstar with a 3.8, it started running rough and then the check engine light started flashing, we stopped driving it, pulled the codes and it was a p0303, we replaced the spark plug...


It's common for ignition coils to go on these vehicles. If you have a spark tester (auto parts store) install it on your #3 plug wire and check for a strong spark. By swapping the wire you obviously eliminated it as a possibility. There's always a chance that you have a compression problem or ad injector problem but chances are it's just a bad ignition coil. Mark the wires then remove them. You can remove the coil without accessing major components but it will be tight. Disconnect the connector and remove the bolts.

If not, look at the coil for hairline cracks. I see a lot of coils go bad and the vehicle will run worse when it's damp or raining out. Good luck!

Cde po301


A P0301 code means that the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #1.

Symptoms may include:
· the engine may be harder to start
· the engine may stumble / stumble, and/or hesitate
· other symptoms may also be present

A code P0301 may mean that one or more of the following has happened:

· Faulty spark plug or wire
· Faulty coil (pack)
· Faulty oxygen sensor(s)
· Faulty fuel injector
· Burned exhaust valve
· Faulty catalytic converter(s)
· Running out of fuel
· Poor compression
· Defective computer

If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Cyliner 1 misfire, codespo301, po316, po301b, b1352


A misfire can be cause by several factors. here are a list of things to check check spark plug on that cylinder and check coil and wiring for coil. check cylinder compression on all cylinders if one cylinder is less than 10 psi different from the others that can cause a miss, last but not least check injector pulse using a noid light for injector pulse if pulse is good then injector is bad replace and that should solve your problem. Good luck and contact if you need more help. Thanks for using FIX YA

i've heard of the 5.4l's with the "cop" set up devolping moisture under a coil. if it hasn't again that is most likely the problem. to prevent this you could remove each coil and apply dielectric grease to the tops of the plugs.
