Bad Annoying Idle
I have a 1989 corvette L98, it has a very intense vibration at idle and it only got worse after taking it on the highway. It started when I got stranded due to no fuel. Since then I replaced my fuel tank, fuel sending unit, fuel injectors, fuel filter and cleaned my throttle body while getting a new iac and tps and gaskets. I also had it tuned up with a new cap and rotor with plugs and wires and so far the idle is still as rough. The car drives perfectly but the idle is incredibly rough and I'm afraid of causing long term damage by continuing to drive it with the idle, any ideas on what it could be?

When the tank went empty it may have picked up sludge that got into the lines. A clog hould cause you issues all over the tach range, not just at idle, but it's a maybe????
