I picked up some Mustang injectors from the junkyard, everything looks the same, plugs up the same, only thing different is the 4 holes instead of 1. Well I installed them today and now Tank sounds like he's a cammed SBC, barely idles and then revs high. I reset the computer but it won't idle or run right. Any suggestions? It's a 92 xj 4.0

What is the injector #, from what I've read you should be using the 19# Injector, also a lot of guys will buy them re manufactured vs. getting them from the junkyard. this way they are sure that they work properly.
