Cobra computer
24 lb injectors
Stock calibrated MAF sensor

Those three things in combination are correct.

Pull codes and see what the computer thinks is wrong. My guess is that you've got a vac leak someplace that's leaning out your mixture. You may also want to check fuel pressure and ensure that it's correct. Is the meter you're using out of a Cobra or is it a GT/LX meter? From what I understand, there are differences in calibration between the two.

no and no. you need a meter calibrated for 19# injectors if you have the cobra computer.

you can not use a meter calibrated for 30's from a gt. your best bet would be to find a pmas/pro m dealer and get one specific for the cobra computer. you could get a c&l and get the appropriate tube, but pmas/pro m would be my first choice.

I would personally ditch the Cobra computer and get a regular 5.0 comp., and get a PMAS MAF calibrated for you 24's. What is going to happen if you ever want to upgrade? You will surely need a chip at that point.
