DEAD WRONG IT HAS BOTH.!! VIN F TOO.

the CMP and CPK sensors both must be good and cam actually turns and cam timing in spec or the ECU cuts spark then cuts fuel..

THIS IS THE 2.2L NOT 2.4L SO NOW i HAVE BOTH PRESENTED

1st run scans for fault codes.

mcdevito75 here, Sounds like the idle speed motor or the idle speed sensor is no good. Your local shop can check this out for you.

Could be fuel filter. This will restrict a lot. If it is automatic it might be your transmission control module. Your check engine light should be coming on if it's not already.

could be afew things. vacuum leak, one dud HT lead, could be the water temperature sensor, O2 sensor, best to get it checked and get it read for fault codes

you must take your car to an service center with a diagnosis computer with the correct software as
this light is a warning lamp you must have it checked as it can or may lead to serious damage

Ck or replace your MAF sensor. First sensor in the duct coming out of air filter. It controls the air/fuel ration

if the car is stock i would replace your oxygen sensor. you may also need to clean out the MAF sensor.

The 300M is equiped with a rev-limiter. The technology is designed to protect the engine. It keeps you from blowing it up when it has no load on it...If it is driving and shifting ok, and you have no check engine light on...there is nothing wrong.
Why would want to rev the engine past 4000 rpm in neutral anyway? Max torque comes in around 3950 RPM...
If you keep reving it up in neutral you might throw the computer in to LIMP mode, then you wont go no where.
Hope this answers your question...
