Get the OBDII codes and we can help you, with my experance it's a vacumn leak or IAC malfunction, do you hear a vacumn leak on start up? sometimes they can be cleaned, IAC is located on the throttlr body.

Get the OBD2 codes read to determine what (and how many) errors are being reported by the check engine light. Most auto parts stores will do this for free, and decipher the codes, sell you the part too!

My crysler 300c check ingine light on and wont revers and it only goes 40to30 rpm why?

You would need to take the car to a shop or auto parts store and get the computer scanned for trouble codes.
The codes will direct you in the area of the problems and what to test.

My 99 maxima car rpm goes up and down olny when i hit 2,000rpm's and will not go over 45 mph what could be wrong with it ?

If your driving along light on the gas & as the transaxle
shifts or later the tach or rpm flairs up,then the transaxle
is slipping

There is no fix for that ,other than having it removed & rebuilt

Need a trans repair shop for that

p1545 is a throttle control malfuction code

You can try to reset the throttle body by opening the hood and drivers door then turning your key to the accessory position. You will hear the throttle body whir and click. It may take up to two minutes. Afterward, the car will relearn your habit of driving and adjust accordingly.

Check ingine code says there is a air leak somewhere

evap leak can be due to a gas cap not tightened fully. Did this code come up after fueling? If yes, have auto parts store erase code for you at no charge.
