A P0305 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. Did the codes appear after the new plugs/wires were installed? What about new Dist. cap and rotor?

Did you use quality parts?

Check for vacuum leaks (including manifold gaskets) on Bank 1 (Driver's side).

Also swap Cyl.#5 injector with another cylinder and see if the misfire code changes.

Are you sure #5 plug is firing?It's possible the cat may be restricted, but I would first swap #5 injector with another cylinder and check for vacuum leaks.

A plugged cat/exhaust system will not set a P0171.I'd say first check the intake manifold gaskets (two of them) for leaks. There are other things that could be causing those common but pesky p0171 and p0174 codes. I would recommend you search the forums on those two codes as they're pretty common.

The P0442 code is likely not related

SOURCE: where are the spark plugs on an 05 3.5 liter chrysler pacifica?

Each of the plugs has it's own coil so they are under the swaure coil, you won't see traditional spark plug wires, look for sets of two wires headed for ~ 2.5 inch square block, three plugs can be seen in front of the large plastic air plenum, the uther three are underneath the plenum. Takes a real handy DIY person to do this as there are plenty of things to remove before the plenum comes off. Take good notes on how you remove things, I missed a lever that is part of the idle system and throught I messed things up bac\d, but when I located the correct place to attach the lever it was fine. Also be careful and not break a connector to the individual coils. I did, but was able to glue it together...

If the light isn't flashing, it is safe to drive. If it is flashing, then catalytic converter damage can result. Have a parts store check the codes for you and come back and post the code.

Your MAF may be dirty and needs to be cleaned or replaced. You may have a vacuum leak.

In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
Inspect all vacuum and PCV hoses, replace if necessary
Check for a dirty fuel filter and proper fuel pressure

My 2008 Pacifica was just in for service for an engine oil leak, I just got it back yesterday and the yellow "malfunction" light came back on. What could this mean?


The engine malfunction or check engine light could mean a whole number of different things, you need an obd diagnostic tool to read the trouble codes...

was the light on before you took the vehicle in for repairs, or did it come on after repairs, if someone has worked on the engine, all I can suggest is check that they haven't left any electrical connections off any components, that will cause the light to appear...

What does the P done code mean in a Chrysler Pacifica?


'P' stands for powertrain-codes will be concerned with engine or trans and are generic, that is they are the same no matter the make of vehicle-OBDII protocol. I.E., a P0171 means a lean reading on bank 1, on a ford, chevy, volvo, toyota-universal general code for all makes and models.

My chrysler pacifica had a code p0420 what does that mean


catalytic converter is running below expected threshold-in other words, the sensor is telling the engine computer the cat is not doing it's job, that is to clean up any unburned gases going out of the exhaust. It can mean you need a new cat, or you have an exhaust leak-could also be cured with a new O2 sensor, or check the connection or wiring to the O2 sensor. Will not affect the way the vehicle runs, but usually indicates the car is not 'lighting off; (getting to operation temp) anymore.

I have a 2007 Pacifica and the check engine light came on and a code PO 420. What does that mean?


P0420 is catalytic converter efficiency code. This code usually requires the PCM being reprogrammed or the catalytic converter replaced, sometimes both. How many miles are your pacifica? Emissions control equipment should be covered by an 80k / 8 year warranty.
