Big misfire issue please help
The beginning of the week, i finished my cam, injectors, springs, pushed, and longtube install. The car fired up and ran great. I have been breaking it in pretty good, taking it easy except for 3 or 4 quick rips. Today I fired it up, and it seemed to try to flood itself out, but i revved it up and it went away, but when i got on the road and got it above 4000 rpm, it stsrted missing. I habe no idea why. Is it a defective injector? Loose rocker bolt, ruined cam, ruined engine? Should I unplug the battery and reset the ecu? I'm freaking out and have no leads at all. Any input would be a huge help. Thankyou

Make sure you didn't melt a plug wire somehow lol. Also check all of your plugs, I've had one crack while doing headers before that didn't start arcing until a week or so after. And do you have the car tuned, or did you just install the cam/injectors and start driving it around tuneless?

What is the nature of the “missing”. Does it seem to miss intermittently...a cylinder miss here and there? Or does the car stumble, and bog down? I’m thinking electrical/continuity/wiring issue. Because the car ran ok to your liking, before, I don’t think that the tune is your issue, although with your mods, you require a tune.
