Default 96 Bonne spark plug problems

I took it upon myself to change the stark plugs in my 96 Bonneville SE. When removing the old plugs, the gap on them was between .07 and .075. According to everything I read, the spark plug gaps should be .06. That is what I set it at when I installed the new plugs.

Now with the new plugs and wires. the car seems to be idealing fine, but when I accelerate, it seems to have trouble accelerating and switching gears. It 'put puts' when I accelerate. jerky acceleration. No smoke out the rear.

Check engine light is on and the traction control kicks in and off sometimes.

I obviously haven't been driving that far on it while it has been doing this.

One more thing, but I don't think it should affect anything I spilled quite a bit of stearing fluid on the engines/ wires. The plugs where already in.

Please help!!!!!!!! I'm assuming I'm going to have to re-do all the plugs with a different gap, but I don't understand why it wouldn't be .06 as recommended. I don't want to take it in because I would lose my whole profit by doing it myself.

Your gap should be good.

When did you buy and install the plugs?
When did you buy and install the wires?

Did you change one wire at a time and ensure that all the wires were firmly seated on each plug and coil pack?

Did you ensure that the #4 and #6 wires are not touching the O2 sensor wiring as it'* pretty close back there?

Another possibility is a vac leak. Check over your vac lines, do they look dry or cracked? Your gap is fine. .060 is stock settings, or was that .065. Well, it'* one of those. I'm guessing you have a vac leak, or a wire is grounding out.
