One of my buddies "tested" my injectors, and now it's running crappier than ever. I think that he may have mixed up the injector firing order. What's the easiest way to check?

The only thing that I can think of is to swap two, see if it makes it better, then swap back if they don't. Is there a better way?

It'a 94 ZJ 4.0

I searched on injectors, and found nothing useful :confused:

Each injector has two wires to it they should be in the following order..... the grounds are dark green with orange tracers which will be on every injector in adition to the following..


#1----white /dark blue tracer
#2----tan
#3----yellow /white tracer
#4----light blue /brown tracer
#5----pink /black tracer
#6----light green /black tracer

You are the man! Thank you. :D
