I never considered the fact that it might be 'gas prices going up'. Maybe it's because that's retarded
No, this is engine related. I've been using the same 91 octane gas and putting the exact same amount in each time recently, which was 3.0 gallons, just to see how my mileage was. and substancially was decreased as opposed to 3 weeks ago and what 3.0 gallons would do.
Ok so i've taken into consideration that maybe i gapped the spark plugs wrong. But lets say that isn't the problem, what's the next thing to check? and how to check them. i need to know HOW to as well
come on, i need a diagnosis here!
