Now that you've told me everything you've done to the vehicle, now tell me what the vehicle is doing drive ability wise, don't leave anything out. Tell me what the codes on the computer, including the one stored in the history, be exact your explanation of how the engine runs out of all RPMs including but not limited to the engine surges at idle etc. Tell me any insignificant thing that you believe will not help. And tell me how many times it took you to put the timing belt on correctly.
There's a thread going on right now about how hard it is to set the timing just right in the cruiser. Even the certified mechanics say it's difficult to get it right but the problem is that's it's a pain to take it apart again to check it.
The other thing to try is the IAC (Idle Air Controller). It's located attached to the throttle body on the back side. A black plug-in. It can be cleaned or replaced and has helped others with idle problems.
I know that you check the timing but check it again:
below is a story of a person that has the same problem that you have any finally fixed it the timing belt was off tooth.
I started disassembly from the top, just enough to get the top timing belt cover off and see the cam sprockets, and guess what. They appeared to be off by a tooth.
Fully disassembled, and when I got to looking at it to line it all up I realized something, the motor appears to be sitting at a slight slant, so although the lines looked even and lined up, the where actually slightly off. Tilting my head to the side to adjust for the engine tilt, taking extra extra care to line the marks up, I got what looked to be lined up timing marks.
This time, before putting everything back together, I said what the heck.
I got a friend to crank it over while I watched everything under the hood. The engine actually started and idled fine. Woo Hoo!
Put everything back together and she purrs like a kitten now.
So the morale to the story is, YES, you need to reset the timing marks, cause they are off.
I currently have started on a 2nd cruiser that has 97k and a water pump leak. Tear down was fast and easy, considering myself somewhat of a pro at it now.
Waiting for some ordered parts to come in and I will be making my approach on reassembling a 2nd cruiser and hoping I don't make the same timing mistake twice. Plus knowing this time I will crank, start, and run the engine for a minute before I reassemble it all.
I hope this chapter in my PT Cruiser book proves itself helpful to any and everyone out there that is adventuring into the timing belt area of a PT Cruiser, and if your in the central IL area, give me a shout and we can work something out to get yours fixed.
