Hi, My name is ***** ***** for the delay.
I will do my best to assist you
how much fuel pressure does it have?
is the 300 code the only code you get?
yes,,the 300 code is a random miss-fire
it pulls well at wide open throttle?
the first thing you need to do here is to check the fuel pressure,these must have no less than 55psi at all times
most times when the light fashes like this,it could have a clogged/bad catalyst converter
stand by,,i will give you more tests/checks for the 300 code
lets test that fuel pressure,,you may have a weak fuel pump[common]

if it runs rich,you will get another code with the 300,,perhaps a 172
there is no way to get fuel in the oil...if you do have some,,the intake gaskets are blown
it is likley the lower[if this is the caase]these do blow from time to time because there is really only four bolts holding it down.2 in front and 2 in the rear
not really,,it would be best to remove the upper
you would break your injectors
the intakes arent too bad on these..the distibuter is the most aggravating part
