[partyd]

Today i purchase a 2001 pt cruiser with 110k miles touring with leather
everything works ok but there is a little missfire on the engine
there is no engine light on but i found 3 codes


0351, 0352, and 1193

351 Coil #1 is not reaching peak current at the right time
352 Coil #2 is not reaching peak current at the right time
1193 Inlet air temperature sensor voltage is wrong

any idea where i can start to look for the problem and fix it ?
thank you

From PT Do-It-Yourself.net:

P0351 - Ignition Coil Primary # 1 Circuit - Peak primary circuit current not achieved with maximum dwell time. Possible causes include:

Ignition Coil
ASD Relay Output Circuit
Ignition Coil Driver Circuit Open
Coil Control Circuit Shorted To Ground
PCM

P1193 Inlet Air Temperature Circuit High - Inlet Air Temperature sensor input above acceptable voltage.
The fault with the IAT sensor indicates these possible causes:

PCV System - Visually and physically inspect the PCV system. Check for the PCV valve disconnected. Check for an incorrect PCV valve. The PCV valve must meet OEM specifications. Check for damage or kinked vacuum hose.

IAC Motor Passages – Check the throttle body to ensure that it's clean and the IAC motor pintle is not hanging up. Inspect the IAC Motor and passages for any obstructions or damage to motor.

Vacuum Leaks – Start the engine. Inspect the vehicle for external vacuum leaks. Inspect the engine for internal vacuum leaks. Check for loose or disconnected hoses on the PVC valve, engine make up air hose on the manifold and or air box, power brake system, throttle body, head, head gasket, intake manifold gasket and EGR valve. (Aluminum heads and engine overheating, if you experienced any, are a bad combination which can result in a warped or cracked head or leaky/blown head gasket, all of which can also cause vacuum issues.

Air Induction System – Check for dirty Air Cleaner, Foreign material trapped in the air intake tube and leaks in air Intake tube connection, Air Cleaner housing, etc

Trottle Body and Throttle Linkage - Inspect the throttle body plate carbon build up or other restrictions. Inspect the throttle linkage for binding and smooth operation. Ensure the throttle plate is resting on the stop at idle.

thank you , i hope is not the head gasket there is a also a noise like a broken muffler that i didn't mention i when to have it fix this morning and i wast tol.
nothing to fix that i need a mechanic and the donut needs to be replace
do you know what is the correct part name for this ? it attaches to the flex section of the muffler close to the engine, the noise comes from under the driver side

also the car runs great when it is cold but after driving for 30 minutes
the car idles bad ,jumping a little the car and engine like it wants to missfire

thank you

The noise your hearing might be the flexable joint of the CAT. If it is, it can't be repaired. It might be replaceable under the emissions warranty depending on your mileage.

Running rough after it warms up could be one of your 02 oxygen sensors. They really don't come into play under the car warms up. If the sensor is bad it will send incorrect input to the computer.

than you ,
that what it is, the flexable joint of the CAT dealers wants 1,100 and repair muffler place about $300.00 so i am going to take it out and fix it some way

i also found another problem in this car, i remove the oil to change it and found 8 QUARTS OF OIL

why someone will put that much oil in a pt cruiser ?

why someone will put that much oil in a pt cruiser?

In the old days you would overfill the crankcase so the tappets and other moving parts would NOT make noise when the engine was running.

I have no clue just replace it with 4 quarts of clean oil and it runs ok the engine is good, but i still have the same problem of the engine jumping a little at idle
i am thinking maybe the timing belt was not install the right way

i notice ther is a lof of work to do the timming belt

have anyone pull the engine out to do the timing belt ?

[partyd]

solder a new flex section on the cats noise problem solve
there was a plastic cap on the PVC valve and the hose from the other side was also close
new pvc hose and remove the caps no more codes or engine light
but car still idles bad or the engine jump every few second

I can see that the timing geld was replace is it possible the install it wrong ? or that there was any damage to the valves ?
can can i know that with out opening the motor ?
thank you
