    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

2002 pt cruiser is idling rough, what could cause this and how could it be fixed?


check to see if there are any codes in the computer that could help. then if you haven`t had a tune-up for a long time it may be due, spark plugs, fuel filter, etc. it could also could be a fuel pressure problem, get the pressure tested with a gauge. also clean the throttle valve a if they get dirty it can cause idle problems.

What could cause it to idle rough


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.

2004 pt cruiser turbo idling and running roughly


c99fd777-e303-4157-9a0b-18509a067e72.gif you would need to do a running test. but if its worse with new injector. then it can be the dispack fault. it feeds the spark plugs. have seen some were the unit has leaked. and made like a cement on the shaft that is the inside of it come out and dropped down the shaft. also the rubber will go white like water marks. check them to make sure they are the same if it does look like what ive said change it. they are not dear to replace.

Does the vehicle turn off, run rough, or hesitate?

My 2003 PT cruiser's engine light came on, then the car started running extremely rough. It became so bad, I had to pull over. Sitting idle, it seems to idle a little rough, but when I gas it gas, it would...


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
