Remove the intake hose from the throttle body and spray it down real well with throttle body cleaner. Manually open the flap and clean back in there to. Allow to set a few minutes to evaporate and put it back together and see what that will do. It's good for it even if you don't fix this issue.

The engine might stumble a bit when you start it back up because of any carbon build-up that you sprayed into the upper manifold, just keep it at a higher than normal idle with your foot till it all clears up.

While your at it, you might take the negative batter cable off while your cleaning the TB to reset the computer and clear out any old fault codes. Can't hurt.

it's only 4 bolts. take it off and clean it. then you wont be spraying more crap into the motor. you can take the idle air control valve off the throttle body and clean that too. the IAC is probably the part that is dirty.

So I wonder why that was recommend? On the PT's engine it is nothing more then an air valve? I mean it won't hurt just not what I would have recommend for a hesitation in an inductive system such as it is on a PT?

Talking Re: throttle body cleaning?

Thank you ALL. It was recommend in this forum to clean the throttle body as a way of ridding my 04 of the hesitations he's having at idle, stop signs and start off's. This hesitation happens even when the engine is warm.
I have had to replace 2 cam sensors at 2 different times. Both times the engine did this for a couple weeks before the codes came up.
I have had him for 2 years in June. I do regular maintenance and have replaced 4 spark plug (2 were cracked)and the water pump because of a leak. While it was torn apart I also replaced the timing belt.
I am grateful for any help I can get.
Can you all think of another reason for this problem?

Did you change the spark plug cables in your tune up? The factory ones are crapy!

Thank you NitroPT, BustedPT, Crewzin, rob342, Rocketman8060.
The wires were new in 2011 and are MOPAR.
This hesitation or BURPING has been a constant problem since my purchase. I have blown the CamShaft and CrankShaft sensors TWICE
At the last replacement it was recommended that I replace the ignition coil? and the Plenum Gasket ?
I have read here that they RARELY need replacement. I believe you all. But could they be right? Could this be the reason for the burping or hesitation at idle and acceleration???

If you can get a vacuum gauge and connect up to a direct vacuum source from the engine it may tell you a little more what is going on? I would say have the engine checked for cylinder leakage as well. If you are not showing a code and have had the ram checked for stored codes then you may simply have a mechanical condition that is not emission related.

I would change the pcv valve [$10 at mopar] and clean the little filter in the air box that goes to the valve cover. Spark plugs--champion re16mc @ .040 --Mopar plug wires are fine, and they fit great. I could tell you a long story about Belden wires and ngk plugs, but I am running low on valium.
