Jeep jerks forward when accelerating

[Irohk]

My Jeep is a 5 forward 1998 4.0L 6 cylinder TJ and after overheating it started jerking forward when I accelerate. I already changed the plugs and cleaned the fuel injectors but it still jerks forward when I accelerate, this normally happens around 2000 rpm. I scanned it but the engine check light isn't on, so codes aren't showing up. Someone told me it could be a sensor that went bad, so I'm wondering if anyone knows what sensor could possibly cause this issue.

For anyone interested or having a similar problem, I changed some of the plug wires back to the original set I had taken off with the old plugs and it’s running like normal now. Still going to monitor it for a few weeks, so I’ll update if I run into any issues.

Why did it overheat?

The radiator cap wasn’t properly tightened so the coolant got out of the radiator. The cap is a 13 lb.
