So my car started sputtering and misfiring at idle and low speeds coincidently right after I had just finished beating a 06 Ford focus in a little "street race" haha. So I plugged in the scanner and it gave me the P0300 "random/multiple cylinder misfire" code. (It told me specifically cylinders 2 and 4 were misfiring). So I replaced all the spark plugs and ignition coils (having bought the car 7,000 miles ago I had no idea when they had been replaced last). Now my car is still sputtering at idle and low speeds but the scanner is not giving me any codes.

Any idea what I should look at next?
BTW. I had previously replaced 02 sensors and MAF.

It is a 5 speed

 

check your fuel supply and for loose connections. you can spray throttle body cleaner around the maf and if idle changes you got a leak. doesnt sound like a failed component, sounds like a critical air leak or fuel supply

 

I found out that the air hose leading to the MAF had slipped off. So I just reconnected that and I'm back in the game. Thanks for the help!
