can i get help on what exactly i need done please

a p0300 for chrysler is general or multiple cylinder misfire is detected, first wat size engine and how many miles?

It appears that a 'qualified' auto mechanic is in order to diagnose and perform hands-on testing of these issues... That is what needs to be done to prevent guessing at it! Copy and past the link below and you'll see what I mean: http://engine-codes.com/p0355_chrysler.html Use the > engine-codes.com link that comes up!

First thing,have your battery tested and post findings.someone here will try and help you.stay calm!there are good people here..

CAR NEEDS PROPER DIAG ON BOTH CODES.THE FLASHING LIGHT MEANS MISFIRES AND WILL CAUSE OTHER DAMAGE IF NOT REPAIRED ASAP.
