#10 of 21 2005 PT Cruiser bucking & sputtering by sllackey

Oct 06, 2011 (12:03 pm)

We have a 2005 PT Cruiser with aprox 116,000 miles on it. Recently it starting having the same issues everyone else is having with it bucking, sputtering at low speed until i can pump the gas enough to get it past the issue and up to a better speed. It does this off and on and the engine light is on when it happens. We have replaced the spark plugs, the spark plug wires, the cam shaft sensor, the ignition coil and the gas cap twice. all these items are what come up the the little check engine light gadget is attached to the engine for a possible fix. It help for a little while and goes right back to doing it all over. sometimes i take the gas cap off and it get to where i need to go but it starts happening again. Yesterday we had a shop tell us it was the wiring harness and it will cost a years worth of car payments to fix it. The problem is that Chrysler has so many of them on back order they cannot not even tell us when we can get one. I am so depressed with this car right now, i also have a senior parent living with us who i need to be able to take places and this car is not dependable right now.

Im sorry to hear that you are having similiar issues with your PT that I had with mine. I wouldn't wish this on an enemy. With that said, I replaced the cam shaft sensor along with the crank shaft sensore and I have had no problems for 3 weeks (knock on wood). Try that and see if it works.

Even after replacing our cam shaft sensor with a Morpar brand, it started again. This time we took it back and found out the timing belt had skipped a tooth and was causing all the issues. Sometimes it would run and sometimes not. Could only go about 10 miles before it would act up, now it seems i can drive forever, no problems so far. I have heard that it is a PT problem that hits about 100k miles, we made it to 116k.
 Good luck,

I have had the same problem and was told that it was the cam shaft sensor. The light comes on and stays on. Last night though it did something different. The car was cold (only 20 degrees outside) and it started up rough (no check engine light) and then the check engine light flashed 4 times and then went out. What worries me is that then the thermostat went up to the halfway mark (usually runs the 1/4-1/3 mark when warmed up). There is no way the car was warmed up that quick. It was still blowing cold air out the vents too. Anyone else have this problem?

two days ago i was afraid to drive car because of performance. last night the temp got down to about 25 degrees here in tampa area. this morning check engine light was off and car ran perfectly seemed to have more power than ever. i noticed this last year when temp went down. maybe someone can use this info.

This problem drove me nuts for almost 2 years the warmer the weather the worse it got. No one could figure it out! Lots of money wasted.
The solution was to apply conductive cream to the spark plug wire connections at the coil and the spark plugs.
I now do this at every oil change as the cream dries over time .
Never saw the problem again.

After we replaced most of the same stuff you did and it was still doing it, we took it to an auto electrics specialist. It turned out to be the timing belt. Looking back on several of the diagnostics printout, it was listed at the bottem of the list as a possible. It was a little expensive but the problem has gone away.

We noticed that the check engine light stayed on and we had it checked out and they said the number 4 cyl was miss firing. We changed the plugs and checked the wires and that did not fix it so we took the car to the dealer and they said the problem was in the heads, possible cracked some placed. we have less then 100,00 on this car, why would the head crack with such less miles. Are there any recalls for this.
