That is your est wire. You have to unplug this when you set the base timing. Unplugged, it prevents the distributor from advancing. It should run 100% better when it is plugged in. Plugged in, it allows the computer to control the advance.
It should drive like a new car now.

When this wire is unplugged and then you plug it back together....you should probably set a trouble code 42. This is standard when you set the base timing. To clear the code, just disconnect the NEGATIVE battery cable for about a minute. This will clear all codes stored in the computer and give you a fresh clean slate.
