my car has started puling the wonderful p0300 code... random cylinder misfire... well it started an hour or so after filling up the tank. Think it could be a bad batch of gasoline? ive neaver experienced having it but i have heard other people say they got some bad gas before. i havent done any other recent work to the car and didnt know if it was a coincidence or what. just wanted to see what everyone thought before i started replacing plugs/wires/ect/ect
thanks for any help!
 


just turned about 76,000 and im not sure. i bought the car with 73k. i was gonna wait to do them next spring with the rest the maintence that should be done yearly, but its lookin like it may need done sooner if its not the gas issue. i just find it weird that it started after that tank of gas
 
It could very well be some bad gas. Just run the tank out and put some good fuel system cleaner in and fill it up. You are using 91/93 right?
 
shell 93 or sunoco 94 if im near the side of town sunoco is... this was a different shell station than i usually use though so thats whats makin me think torwards the bad gas idea.
thanks for your input
 
"bad gas" is a myth. if you car runs different because of different tanks of gas then your tune isnt right to begin with. i can fill up literally anywhere with any gas 91+ and my car runs exactly the same.
