I finally got the car running, changed the plug wires, and fixed the loose connections. Now the car is missing like a ****.

Sumb!itch, this thing is whipping me to death. All the plug wires are connected securely, everything looks shipshape, but damned if this thing isn't beating me down.

I don't even know that I'm even asking a question. I'm just kinda venting...

 

Clogged injector? All cylinders firing?

 

yeah, checking for fuel would be a logical step. Get a long screwdriver and hold one end to the injector, put the other end to your ear. You'll want to hear a steady "tick...tick...tick..."

If the injectors work well, i'd suggest looking inside your distributor.

 

doh! guess I didn't explain....

no, it's misfiring...and no, it's carbed. Carter 600 carb on a 400 sbc. And I have the firing order right, and it's getting fuel. It seems wierd. I need to probably reset the timing....

 

Sorry, I assumed an 87 firebird would be fuel injected. Have you tested the wires for equal resistance? You should test between the terminal inside the cap and the end of the wire before it snaps on the spark plug. A large difference on one wire, with greater resistance than the rest, could suggest a bad terminal on the cap(possibly corroded) or a bad wire. You can test the wires themselves too, resistance shouldn't be more than around 30k ohms. If that is all good, I'd start checking plugs.
