2005 Chrysler Sebring

Hello,

Go by your local parts store and have them pull codes, write them down and post.

.

Lack of acceleration, chugging, hesitating, bogging etc. Could be caused by one of the following below.

Inspect and test all the following listed below and get back with some results

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard.

To definitively isolate the cause of your problems can be done in a much easier and less time intensive manner by performing a "Drive Test" with a capable scanner and a technician with the skill to interpret the data.

*Note* All scanners aren't created equal. Your standard "AutoZone" scanner won't do this job.

This may cost you a little more up front, but believe me, it'll cost you waay more in the long run if you manually inspect every single component on your engine that could possibly cause a drivability issue.

A drive test will display all of your engine's operating systems as they function in real-time and will graph thier data which can then be compared to factory specs. If any system (ignition, fuel, computer/sensor) is performing out of spec, it'll be easily pin-pointed by a technician with experience. This will get your issue solved and leave no doubts.
