Hi Im David thanks for visiting the site. your code is for a ramdom misfire and could be caused by any spark plug, coil pack or fuel injector
yes a tune up never hurts. but keep in mind replace the plugs and coil pack may not fix the vehicle s code if an injector is causing the misfire.
the best way to tell which cylinder is misfiring is to have the engine running and one at a time unplug a coil pack if the engine doesnt stutter then thats the faulty coil pack. if it stutters put the conector back on and go to the next one.etc....
do you still need assistance?
i hope you were able to fix your vehicle. please accept the answer and leave a 5 star rating for me if you were satisfied with my assistance. thanks. have a nice night.
