Asked by Oct 03, 2014 at 08:39 PM about the 2006 Chrysler PT Cruiser GT

Question type: Maintenance & Repair

have a 2006 PT Cruiser. I keep getting a
mid fire code on cylinder 4. We have
changed the coil pack, wires, and plugs.
Even did the fuel injector in the gas tank. 4
mechanics has looked at it an all are saying
they not understanding. Car seems to run
fine. When I turn the a c on it does have a
small shake to the motor. Nothing that
sound to serious. I'm just curious if anyone
else has had this problem or even know
what my next step can be. We are all
clueless and I want that check engine light
off. A few has tried to override the code to
turn it off but it wouldn't let them do it.

If you turn ac on and it shakes it means your taking on extra load probably not the cause of the misfire. If they tried to clear the code with no success the it has to do with ignition or a bad ground in that circuit. check to see if there has been a recall on ignition switch. here is the link http://www.carcomplaints.com/Chrysler/PT_Cruiser/2006/engine/engine_light_on_and_idles_rough.shtml


Changing the fuel pump would not do anything to help or cause a misfire code. The fuel injectors need the fuel pressure to be 35-45 psi. to operate properly. The 1st thing is to make sure you are working on the correct cylinder. I was an ASE mastertech for close to 30 yrs. and I seen it happen before by other mechanics. If you clear the code and it pops right back you still have a issue with that cylinder. Make sure that the plugs are gaped to proper specs. To make sure you don't have a defective plugs switch #4 with #3 and start it up and see if misfire changes to #3. if it does then you know you have a defective plug. Do the same thing with your coil packs and the plug wires. If there is no change after switching each item(one item at a time)you'll need to check your connections and make sure you're getting power. Also make sure you don't have a bad vacumm leak. I would do compression test if compression is low you might have a bent valve or broken valve spring. BTW if you bought coil pack from advanced auto parts store you might have a defective (new) coil pack. It has happened to me before when I let my customer buy his own parts. Make sure you put anti-sieze on spark plug threads or you might not get the plugs out without stripping the threads on your next tune up. I hope that helps you out. Good Luck. Make sure your battery connections are good. Check all your ground connections because a bad ground could cause all kinds of issues.


The coil pack came from O'Reilly (I think that's the correct spelling. Its the 2nd one we've tried. Tried switching the plugs. Also used the grease for easy slip out on the plugs so they wouldn't strip. However when one of the battery terminals was changed. The light went off. Not to mention. The dashboard lights went crazy a few times back and forth than finally settled. Still at least 5 machines read cylinder 4.

Was it the negative battery terminal that you replaced? If it was, you might still have a problem with your ground. How old is your battery? Does your battery go dead if the car sits overnight? Does the battery terminal bolt onto the battery cable through an eyelet? Or did you cut the cable and put an aftermarket batt.Terminal? Also check your connections at the starter. Let me know so I can try to point you in the right direction.


You may need a camshaft sensor
