Engine codes po325 po442 and air bag light

My 2003 basic edition pt cruiser is running very loud and rough. My engine light came on and they read PO325 and PO442 also my air bag light is on and chimes at me every once in a while. My car has roughly 124700 miles on it. I put iol in my car, about 1 1/2 qts because i know im over due on an oil change. could the oil be a problem or something that would cause the car to act funny and the codes to come on.

Determine what the code descriptions of errors are. Then check and replace as needed.
Airbag light indicates problem with airbag system. You must visit the dealer to have analyzed and diagnoses given. Do not attemp to fix yourself. The airbag system, can cause severe injury or death.

Find your air mass flow sensor in the stiff collar of the air ducting immediately after the air filter. Have the engine running and disconnect the plug to the MAF. If this makes the car run evenly again you need to replace the broken MAF. The misfire on plug 4 I think is a downstream event of the MAF not sending the right info to the ECU and consequently not providing the right fuel / air mix to the engine

SOURCE: engine light comes on, stays on, doesn't blink,

The last chime is most likely an audible reminder that the check engine light is on. It would be advisable to get the car scanned to see why the light is on. Even if the car seems to be running ok, your fuel economy or emissions could be worse than they should be.

SOURCE: I have a 2003 Chrysler Voyager mini van and the

wow a lot of codes, lets start with them....

P0351 ignition coil A primary/ secondary curcuit

P0300 random misfire detected

P0301 Cylinder 1 misfire detected

P0304 Cylinder 4 misfire detected

P0442 Evaporative emissions leak detected (small)

P0445 Evaporative Emissions System Purge control valve circuit shorted

I guess the first thing i would do, is insure that all the maintenance on this vehicle was up to date. Do an oil change and a tune up. Make sure you use decent spark plugs as a fouled plug or bad oil could cause a misfire. After you do the tune up, try running it some more, if the problem persist, you may end up having to replace the coil.

The evaporate emission leaks. These, especially the the 442 can be either a loose gas cap or a small leak in the vacume system. Insure the cap is tight passed several clicks and listen the the motor as it runs and try to hear any leaks. If you find a leak replace the faulty lines. Also inspect the vacume line for cracks and breaks.

Wish you luck, we are hear if you need more help. Thanks for coming to FixYa!!

SOURCE: Air bag light and chime

You probably need to get your vehicle tested to discover what component of the airbag system has defected. Most likely it is the mass sensor.

My 2003 PT Cruiser runs rough I replace the cam sensor but no better any ideas


not many other reasons why it would run rough if serviced
think its a 2.4 EFI motor timing belt
how many kms has this one done

wont be the crank angle sensor or ecu because its running
any engine light on
if it is on.... there will be fault codes stored to read
check over
maybe 02 sensors
fuel filter change or fuel pump problem
coil packs and plugs
u can clean the throttle body
u can check the air filter

Check spark plugs and plug wires.
