I had the SES light poped up a week ago, went to autozone found single P1320 ignition singnal misfiring with no additonal info. i erased the code and the "Service Engine Soon" light was disapeared. but today it came back on again i went to autozone again read the code with ODB and it shows the P1320 code TWICE with no additional info. i erased the codes again the light is gone but how can i find out which coil is misfiring or which one is defective, and why were there two P1320 codes with no additional details you think the got 2 bad coils now? i am pretty sure the SES light would become active again should i take to mechanic and have him checked with his OBD reader? i am realy confused with this. please help i will appreciate.

 

hmm 2 codes?.. i would assume that one is the old code and one is the new code and the thing just read them funny?...other then that are u haveing any problems with the car.. gas mpg.. sputtering bad idle.. ect?.. if it is a bad coil it should throw the code directing which one otherwise ? ? idk
