Could be tune-up issues, or a bad Air Mass Meter. I doubt that your AIC is causing this. AMM symptoms are surging and flat spots while you accelerate moderately. If this is just happening at steady cruising, I suspect tune up items: spark plug gaps have eroded or plugs are bad-try regapping to 0.024 or just replace with NGKbcp7es, bad dist rotor-resistance between tip of rotor and center contact should be 1k ohms, bad spark plug wires-at night run engine and spray some water on wires- and look for spark leakage, clean electrical connectors to AMM and AIC and knock sensor, temp sensor, O2 sensor and APC. Also clean your throttle body with carb spray.
could also be a phantom bad/dirty ground somewhere. Clean all grounds and also make sure the short ground wire from the alternator frame to the block is secure and not broken.
