Any check engine light?

And it wasn't down, just running on 7cyl and i didn't know. It's got so much more power now.

How did the garage do your timing? Did they unhook the distributor from the computer? The base timing is 0*, the computer handles the rest.

No check engine light associated it. When the mechanic at the shop performed the timing, he used a lab scope. He had the motor over 1000 rpm, made the necessary adjustments and was done. Did he maybe miss a step?....I don't know.
