Make absolutely sure you didn't switch the two plug wires by accident. :eek:

Could be. I would pull the plugs for a look-see first though. How old are plugs, wires, cap & rotor?
all those parts are brand new and i checked to make sure the wires wernt mixed up and there not so im guessing injectors witch sucks becouse i just got it all back together and now ima have to tear it down again

Check for good spark on 1 and 3, then

Sorry to repeat myself but it's Friday!
Before you go through the trouble of pulling your intake maifold again, connect a vacuum gauge and check it.
If you have a steady needle (~16 to 21) until one of those cylinders fire, and it bumps down real fast (~1 or 2 lbs) then you don't have a vac leak, you have a loose, bad, crossed plug wire.

Since it is only those 2 adjacent cylinders that are misfiring, and you ignition system components are new, it could be the following:
1.) Crossed or defective plug wires
2.) Plugged poppet injectors.

You might try running a couple of bottles of Chevron "Techron" additive in your gas, or a can of Seafoam. Otherwise, click here for more info on the CSFI poppet injectors, and click here for info on how to fix them.
