87 Tbi sluggish sometimes?

Ok knowing that the engine has 245k on it, i have a random issue.
Ok very randomly it will just start running crappy, but only under acceleration. But most of the time it runs strong with no issues. I have a new cap and rotor, plugs wires, fuel pressure reg, tps sensor, fuel filter, air filter, i cleaned the iac.

Im starting to think its a bad ground on something in the fuel system or possibly something to do with the timing?
