I've been getting p0300 and loss of power when getting up to speed to merge on high ways idles fine city driving fine just anything after 25% throttle rpms go up but speed slowly go up ive replaced plugs, coils, boost control solenoid, all vacuum hoses, new battery and new throttle body. Only code it gives is p0300 and only getting up to speed.Even giving it 100% throttle rpms rise car barley moves/sputters and bucks.

 

fixed with red top coils store coils where too weak to output spark if any1 else is hav this problem.
