I have just replaced the spark plugs and wires in my 1970 torino and it now runs real choppy and the engine is shaking a lot when idleing, I tried to mess with the idle screw's, I think the air and fuel mixture is not right but when it reaches higher rpm's it does not shake but still sounds super choppy, what can i do to make it run smoother?

Hi:

Not to be disrespectful, but check if you might have altered the firing order when replacing plugs/wires. I've done it. If they're okay, try rerouting the spark plug wires away from each other. Sometimes they can leak current and cause a misfire in the adjacent cylinder.
