I find a paperclip works perfect for a jumper. Quote Selected

That is the SPOUT wire. Unplug the connector.In 87 they started using a jumper plug to disconnect the SPOUT, but in your case you have to unplug the connector. Quote Selected

By the way there are several TSB'S on the timing procedure and octane bar for this vehicle.thanks so much for the help! since i just bought the car i did a oil change cause it was BLACK. i replaced the IAC vlave and the connector. i check the timing and it was right at 10 degrees. the idle is a bit better after but still stumbles/surges then dies. i took a quick look at of the spark plugs and it wasn't horrible but the electrode was worn down a bit on one side. i looked at the cap and rotor and they looked good also. i didnt get any codes on my code reader Quote Selected
