1995 Lesabre Check Engine

code said bad tps, replaced tps, cleared code High idle about 1 min, idle dropped to normal check engine light backRan scan, said tps current error. Tested wires on tps with voltmeter
Both black and white wires read ok
Center wire read 5.0 with throttle closed and .05 open, Should read the opposite
Tried another tps, same issue
So I replaced IAC and mass air flow ( there’s no map sensor)
Reset code, back to square one,
Only thing haven’t tried is computer
Any ideas on what else might cause voltage reading on tps
Can runs ok, just don’t have cruise and overdrive
Thanks
