      could be nothing wrong with sensor and it might be your egr valve or a vacuum leak.

      Kinda hard to look for these cats for your vehicle, last option we have is the dealership.


      Go to a scrapyard and get a catalytic converter, who knows you might get lucky in bagging one

    Why does engine hesitate and loose power.
    Check engine light is on. The problem occurred 20 miles from home. Was able to drive van home. Had to drive 70 mph in 3rd gear at 3000 rpm. If slowed down would loose power and had to slam accelerator down to resume progress. If slowed down to stop noticed fuel ...

      It could be mechanical or electrical there are a lot of causes I can think of but since your check engine light is on you should diagnose your vehicle with a scan tool to know what the stored trouble code in your vehicle is, for you to track the right path on fixing your vehicle.

      Read the fault code that is probably stored. Use a code reader (buy one - $50) and repost with the P-code and I'll tell you what happened and what to replace to fix the car.

      It is possible that your mounting are worn. Check the condition of your engine and transmission mounting.

    I pluged in a OBD 11 scanner
    it read code P0300 random/multiple cylinder misfire detected. P0016 cam/crnkshaft pos. correlation sensor A-bank 1. so how do i fix this. thank you

      The two codes are most likely related. A bad crankshaft position sensor can cause cylinder misfire(s). To replace this you'll first need to locate it. I can't say for sure where it is on the PT cruiser since I've never worked on one but two common locations are:
      1.) On the transmission bell housing where the transmission meets the engine
      2.) Near the crankshaft pulley where the belts are
      If you have trouble finding it, pick up a repair manual for your car from an auto parts store. When you find it, replacing it should be fairly easy. Typically it goes something like this:
      1.) Remove the electrical connector
      2.) Remove the two bolts holding it in
      3.) Pull it out
      4.) Installation is the reverse of removal
      If you find it on the transmission bell housing than make sure you are extremely careful not to drop one of the bolts into the bell housing because the only way you'll get it out is to remove the transmission! Good luck!

    It keeps burning out the ignition fuse??

      You've got a lot of checking to do my friend. If you don't know much about electronics I would take it to a garage but here's what I can give you:
      1.) Check all the spark plug wires for cracked/missing wire insulation and anywhere they could be shorted out.
      2.) Check under the dash by the ignition module for the same. If you have installed any kind of alarm/remote start system than your problem could very well be here.
      3.) Have your ignition coil checked at an auto parts store. I think most of them will do that for you.
      4.) If you have a good bit of electronics knowledge and you really want to tackle this yourself it would help to pick up a repair manual for your car and have a look at the ignition circuit schematic in the manual. This should give you a better idea of how it's wired and where they problem may be.
      Good Luck!

      Could be a hole in the muffler... get out of the car while the engine is running and see if you can identify if the sound is coming from toward the front of the car or the back of the car. You can also look under the car with a flash light, you might be able to see where the exhaust is coming out. If it's part of the pipe you can sometimes patch it with exhaust tape from any auto store. If it's the muffler you may be able to use tape but I recommend replacing it. Also if you have a flexible section of exhaust (especially toward the front of the car) those can sometimes be a problem. If that's the case you'll probably have to replace the whole section of exhaust that the flex piece is in. One last item to check is under the hood, where the exhaust manifold bolts to the engine. If that gasket is bad you'll not only have some noise but also you'll smell exhaust inside the car. Hope you find it and good luck!

      replacing chrysler cam/crank sensors is pretty common. so replacing them has a reasonable chance of success in fixing the problem without actually diagnosing the problem.
      however, if they're not agreeing with their timing references you may want to make sure the camshaft is still in time and that the timing belt is in good shape.
      i would rather get my teeth pulled than do a timing belt in a pt cruiser.
      9/15/2010 pablo
      what if the timing is off how would you set it to its normal timing.

      Do you have a check engine light on? Does the fuel pump hum when you first turn on the ignition? The engine needs spark, fuel, and compression to start (besides the cranking speed).

      Oil sludge could caked over the time and could obstructed the oil passages of the oil pressure switch. I pasted this information from another forum site and i hope that give you the right idea.
      On a badly maintained engine, there's probably already too many deposits for the flushing chemicals to completely remove. But the real danger here is that the chemicals will dislodge enough crud that it will block the very small passages in hydraulic lifters or even clog up the fine mesh oil pump pickup screens. On such engines, you're better off changing the oil frequently, say around every 2,000 miles, so that the natural cleaning properties of the oil will reduce, somewhat, accumulated deposits.

    I am getting a reading that my Throttle Position Sensor is not performing properly.
    What is the easiest way to replace the sensor. I am looking for step my step instructions. Photo's would be helpful as well. I am trying to decide if I can change this myself or if I need to take it to a repair shop. Thanks

      Thanks. I saw this before I posted my question. I was looking for something specific to the Chrysler van. I have spent some time looking at the engine in the van and I am not 100% sure that I have located the sensor.

      Thanks Blackwater. I followed the instructions you sent me and was able to successfully change the Throttle Position sensor. The engine light is now off and the engine is running smooth. I love it when things work out. Thanks again.
