basic SE caliber with clutch problem?
when starting out on a hill using manual in the SE, stalling sometime occurs. there seems to be a slight delay in RPM response when pressing on the accelerator. on a hill this delay in engine response lets to much rearward drift before the clutch catches. is there a way to adjust the throttle to respond more immediatley (RPM) with out the delay? if you come off of the brake and step on the gas pedal to quickly it will stall? Any ideas or common problems?

How long have you had this vehicle. The reason I ask is there have been some updates to that may be helpful but you would have to contact your dealer to see if there are any new flash updates for you car. If so this may be all you need. If not the dealer can help.
This seems to be a new one.

RE: basic SE caliber with clutch problem?
Thanks Me_Also. I have had the SE about one month. I'm obviously not a mechanic, but I believe the problem exists in the throttle(gas pedal) , not the clutch.
From the day I bought the car: when pressing the accelerator with enough force to accelerate up a hill from idling, there is a hesitation in engine revving. After this hesitation(chocking) for a half second , the engine over revs. This is also obvious when revving in nuetral.
on a hill or fast acceleration , the engine hesitates(bogs down) enough to stall when the clucth is released or over accelerates and sgueals the tires .
I driven a manual for many years and realize clucthes take getting used to, but I think this problem originates in the throttle(accelerator).
Is the 1.8 liter just a wimp and chokes on accelertation or needs adjustment?

This is from the service manual the gas pedal appears to be a variable sensor that sends a signal to the PCM telling it where the
pedal throw is at.
All engines used in this section have a sequential Multi-Port Electronic Fuel Injection system. The MPI system is
computer regulated and provides precise air/fuel ratios for all driving conditions. The Powertrain Control Module
(PCM) operates the fuel injection system.
The PCM regulates:
² Ignition timing
² Air/fuel ratio
² Emission control devices
² Cooling fan
² Charging system
² Idle speed
² Vehicle speed control
Various sensors provide the inputs necessary for the PCM to correctly operate these systems. In addition to the
sensors, various switches also provide inputs to the PCM.
The PCM can adapt its programming to meet changing operating conditions.
Fuel is injected into the intake port above the intake valve in precise metered amounts through electrically operated
injectors. The PCM fires the injectors in a specific sequence. Under most operating conditions, the PCM maintains
an air fuel ratio of 14.7 parts air to 1 part fuel by constantly adjusting injector pulse width. Injector pulse width is the
length of time the injector is open.
The PCM adjusts injector pulse width by opening and closing the ground path to the injector. Engine RPM (speed)
and manifold absolute pressure (air density) are the primary inputs that determine injector pulse width. controlled by the PCM.

again from service manual
The Accelerator Pedal Position Sensor (APPS) is a variable resistor that provides the PCM with an input signal
(voltage). The signal represents pedal angle position. As the position of the accelerator pedal changes, the resistance
of the APPS changes.
so have your dealer check the pedal sensor and see if everything is OK there.

RE: basic SE caliber with clutch problem?
I took the car to the dealer today. The mechanic stepped on the gas pedal and immediatley sensed a problem . He hooked it up to the testers and sent the info to chrysler for analyses. It will take a day or two for response.
He didn't find any reports of similar prolbems with calibers from chrysler.
