The code is about multiple cylinder misfire
my car is a 97 Millenia S, 2.5L V6
what will be some major reasons for that? the MPG now is pretty low, only around 15 (mainly local)
hope someone can help, coz i really don't want to go to the mechanics to be robbed.

p0300 is random misfire. the engine is not firing on all cylinders all the time like it is supposed to. easy to diagnose, very difficult to fix. mainly because your post is very confusing. there is NO millenia S with a 2.5. an 'S' has a 2.3 miller cycle motor, with cop system. a 2.5 is otto cycle, with conventional distributor/ign wires system.
