1988 Chevy Beretta Ignition Sequence

Any Help would be appreciated:

I have a 1988 Chevrolet Beretta with 269 666km's on it, that I bought for 400 bucks to fix up myself. I don't know much ( if anything ) about cars, so I wanted this to be my learning experience.

So my problem is that I just changed the ignition wiring for my Beretta, because I noticed white residue/build-up in the connection when I replaced the spark plugs.
The car was running okay to begin with, but it sometimes idled rough and didn't always catch right away on start up. But now, I can feel the car simply lagging in what little power it had left. You can hear the pistons not firing properly, so I'm assuming I screwed up the firing sequence in the ignition coil.
I tried to replace the new wires in the same sequence as the old ones, but something had to have gone wrong.

I was wondering if anybody did know the proper order for the wires in the coil or even the cylinder placement of the engine. ( Btw, the wires weren't labeled properly and were even different brands, prompting me to think they weren't all changed at the same time )

is cylinder placement:
-windshield
135
246
-front of car

coil:
165432

(this is not how I have it now, jst something that I found on google that sounds logical)
