    I'm having the same problem. Changed the plug wires and plugs out but no difference. I did reset the computer after changing out the plugs/wires and then drove about 100 miles at highway speed with no warning light coming on. After getting off the highway and getting into stop and go traffic warning light comes back on with same code. Appears to be a low speed/idle problem as car seems to run smooth after about 1200 - 1500 rpm. Any other suggestions?

    I have the same problem. My engine light keeps going on and off. I took it to autozone and the code that came up was 303 Engine 3 misfire. I replaced the spark plug and the wires and the light went off for about a week. Then it came back on and now goes on if off. It runs go except for when i stop at red lights. Sometimes it to to shake a little. What could be the problem

The P0302 Code points to a misfire detected on the # 2 cylinder. If its stumbling, I would first suspect the plug or wire is bad. I believe the ignition coil on that vehicle is a single coil pack with four terminals, so if only the P0302 code is coming up I would start with the plug and wire. May be time to do a tune up and just replace all the splugs and spark plug wires.

Change the crankshaft position sensor and or the harness wiring in the rear of the engine above the oil filter. This harness goes to the camshaft sensor. This wire harness can short out due wire melting from engine heat. just replace section of wire and you should be o.k. .........runjoe

    This could be my problem since the engine was overheating several times due to the fan not working properly. The fan has been replaced now, there is no overheating problem, but the engine light comes on and the code shows misfiring on cylinder one. I changed spark plugs, wires and air filter, but that did not change the situation. The engine light is blinking when I accelerate and steady when the car slows down, same code 301... But I wonder whether there is any website to show exact position of the crankshaft position sensor and harness...

2002 pt cruiser it had 2 codes p1193 p0302 what do i need to do ?

No , a bad plug wire would not cause a P1193 . Your sensor is bad or you have a wiring problem for the sensor . A P0302 - cylinder #2 misfire doesn't mean you have a bad plug wire either , could be caused by a few other thing's as well . I suggest you take it to a ASE certified repair shop .

Location speed sensor pt cruiser 03 touring car do

It sounds like the module is in limp mode. The speed sensor is most likely the cause, but it can be some other things as well. A scan will give a code stating the problem area.

The speed sensors are on the side of the trasmission that faces the front of the vehicle. There are 2 of them, and they are the same sensor. One is an input speed sensor located closest to the engine, the other is the output speed sensor.

A rich codes is hard to get. Something is restricting the airflow or you have something wrong with the fuel control. Check the air filter and if it is good. I would wonder if you have a leaking fuel injector. Do you know how to do a cylinder drop test? How well does it idle? Does it smell of raw fuel at idle? Is it hard to start after sitting?
