Default Help with surging problem please

91 ls400 motor surges from 800 to 1100 rpm's runs and drive great.
So far I changed the MAF sensor, fuel filter , air filter , removed the throttle body and cleaned it.
Cleaned the top sensor also . I have no codes as I removed the battery cable but it seemed like it was 54 before I cleared them. This thing is driving me crazy tks Danny
