I am working on a 1989 Chevy Celebrity 2.5L V4. It was running fine but it is now running only on two cylinders. Everything pointed towards a bad ignition coil as there was no spark and the wires were fine. I found out that this car has 2 ignition coils - 2 plugs per coil. I managed to remove the faulty ignition coil but I cannot get the new one to mount back on. I cannot see what I am doing since the ignition coil faces the firewall and I have to do everything by just feel. There are 2 nuts that have "free-play". To be more clear on that - the nuts need to be held from the back side while I thread and tighten the bolts but there is no way for me to get my hand behind to the back side. For those of you who have done this, you'll know exactly what I'm talking about. Do I have to remove whatever the ignition coils are mounting to? I'm kind of stumped here.
