On my way home, driving from work jus cruizin it at around 60-65 mph my car starts to blink the CEL. then after about 30 secs it goes away. took out my AccessPort it says nothing, so i take the car out for another drive then it happens again, it starts to blink then it just stayed on. check with my AccessPort and it gave me P0300 "Random/Multiple Cylinder Misfire Detected". what do i do? much appreciated for help..

P.S. heres a list of mods that i have if this will help u guys out...

Cobb AccessPort Stg.1,Injen cold air intake, gfb bov, helix cat-back, Megan racing DP

 

just curious why are you running a stage 1 on your AP with a DP? also imo and most others here get rid of the cai.

but to answer your question i'd say reset the ecu then load stage 2 and monitor to see if it happens again.

 

just loaded stage 2 and i reset the ecu.the CEL still comes on, its still the same codei have no idea wats going on plz help me out guys. thanks in advanced

does the car feel like it's running less than 4 cylinders? if so, might wanna check if your coil pack bolts are loose, this happend twice to me....
