    No it did not fix the problem. Replaced the intake gasket and switch to iridium spark plugs it smooth little and then after drove test for few miles P0303 on again and it rough idle again. Any other solution out there. My last resort is to take it to the dealer. Thanks in advance.

Check the #3 coil. code p0303 says misfire on #3 cylinder.
this causes your vehicle rough idling.

SOURCE: Change the thermostat on 2002 Chrysler PT Cruiser

Hi, i have put together a step by step guide that will help you with this replacement job. Make sure the vehicle is in a cool state before starting this job.


* Drain some coolant into a clean container until the coolant level is below the thermostat housing.
* Remove the upper radiator hose connection from the thermostat housing.
* Loosen the housing bolts and remove the housing.
* Remove the gasket and scrape it carefully from the surface of the housing and the mounting surface on the engine. If the gasket remains on either of the surfaces, there will probably bea coolant leak after reassembly. Some engines use a rubber O-ring to seal a thermostat housing.
* Compare the size of the thermostat to the old one. They are of different sizes, types, and temperature ratings.
* The temperature rating is stamped on the sensing bulb on the bottom of the thermostat. The temperature bulb faces the block.
* When replacing a thermostat, be sure that the thermostat fits into the groove in the block or outlet housing. If the thermostat is installed upside down, the engine will overheat.
* Install the gasket.
* Reinstall the thermostat housing. Refill the system and run the engine or pressure test to check for leaks.
* When the engine has reached operating temperature make sure the thermostat opens.
* You should be able to see coolant circulating within the radiator.
* Another way of checking thermostat operation is to feel the top of the radiator hose or use a thermometer or multimeter with a temperature probe to confirm that the coolant is warming up.
* If the engine is overheating, but the top hose is still cool to the touch, the thermostat is stuck closed and must be replaced.

NOTE
When a paper gasket is used and the recess is in the thermostat housing, it is a good practice to position the thermostat into the recess and glue the gasket to hold it in place. If it falls out of its groove during installation, the outlet housing can be cracked or a coolant leak will result. Before tightening the water outlet housing, try to rock it back and forth to be sure it is flush. Housings are often cracked during this step.

SOURCE: my 2002 pt cruiser lost power steering suddenly

check to see if the serpantine belt is still there. It sounds like like it broke. this belt runs all of the accesories on the vehicle including the water pump. So if this happened it probably starting running hot too

2005 buick lacrosse 3.8 changed spark plugs coils N wires still shakes and sputters rough idle


The basics for vehicle with rough idle, check for a leak of some kind, fuel--egr--vacuum leak. How long since an over-all tune-up? You can check the idle air system? Any applicable trouble codes? To check codes yourself, at the least, you need an obd2 code reader.
If spark issue, sometimes you can use a digital multimeter to do some testing, low tech, non--invasive. With digital multimeter on low voltage setting, engine idling, touch spark plug wires, one at a time, do not penetrate insulation, don't take spark plug wire loose, it's an inductive reading. The point is if you get a reading bouncing off zero, that is where you start testing. I know you changed the coil/s, but sometimes, you need to check ignition module. I'm not saying that module is faulty, I don't know.

Code 303 - not electrical, what should I look at next?


Check for either a leaking injector flooding the plug or a clogged injector causing a lean misfire. Also, the injector driver in the PCM may be bad not commanding the number 3 injector on and off.

No codes? In the following order I would clean the idle air control, change spark plugs, check plug wires, check for vacuum leaks, run some fuel injector cleaner through your fuel tank.

Three things you should check using a good code checker which can read sensor outputs - the throttle position sensor (TPS), the mass air flow sensor (MAF) and the EGR valve. While you are at it, replace the PCV valve.

2001 v6 escape rough idle when cold


To update my earlier repair on the 2001 6 cyl Escape: When cold, and when the ignition was turned over but no accelerator pressure given, the rough idle finally returned the P0303 code again when the check engine light came on indicating that it wasn't caused by the plugs or the coil. FYI, I had replaced the intake manifold gaskets during the original repair and just prior to that I had replaced the fuel filter which was very dirty (I cut it open to see).

The repair manual referred to fuel injectors as a possible problem. I have run three tanks of fuel using different injector cleaning products and am very pleased with the results. Cold starts are much smoother and I am unable to coax out the P0303 code or any other code.

My opinion, change the fuel filter, use a fuel injector cleaner for a couple of tanks, change the plugs if the problem still exists. The coils were not the problem on my vehicle.
