I got this code for a "multiple cylinder misfire" up at the track last night and yea basically id get up into the 4k's in 2nd and just basically lose all power. happened two runs in a row, took the car off the track, drove home no problem and havent touched it since. im thinkin just gettin new spark plugs for a start but if anyone has any good idea on fixing this please let me know. but before it started doin this i ran a 9.67 8th which i was pretty proud of for stock on radials haha.

 

it's usually the plugs and wires, but if that doesn't fix it then take a look at the injectors
