    engine misfires then dies, then runs fine....

    Ok so I was driving on the interstate and my engine did a little hiccup, then it ran fine then another hiccup, ran fine then started misfiring bad and rpms read 0. I gave it some gas and it responded like normal but no rpms. Then on the way home from work it started doing it again but this time backfired then died right there on the interstate. I pulled over and it started right back up and took off like normal. It did it about 7 or 8 more times before i finally made it home. It didnt throw any codes whatsoever, what the hell is going on?

    sounds like a fuel issue to me, like your fuel pump is failing. Check pressure at the fuel lines, also make sure all wires are ok, and plugs aren't fouled.

    are you saying the car was running at one point but the tach was at 0? If that's the case it sounds like a bad ground wire. Check your battery cables.

    yeah car was running with tach at 0. one time while i was parked the tach was at 0 and it was idling, I took off and it eventually started working. I dont have a pressure gauge to check, but what does it need to be at?

    I visually checked the wires that I could see, they all seem to be fine
