For idle, both will work. What do the plugs look like? I'm guessing its "tuned" up, so if that is the case and assuming everything else mentioned in this thread is kosher, then its time to fiddle with the pump. Do you have the long screw driver and Allen wrench that is used to adjust the MFI pump? If so go two clicks to the left and drive it. Remember to write down how many clicks you went because too much fuel can cause the car to bog and die, to little as well. If you can tell its getting better keep going until it idles, if it gets worse, back off and go the other way. You do not need an afr meter to do this, get it to idle right, then you can buy one if need be.
