I doubt the tps is your issue. Likely the iac is needing cleaned or the vss is bad.
You have an 89 and it should be a maf car. So the pcm uses the signal from the vehical speed sensor (vss) to keep the idle up when you come to a stop and inbetween shifts.
you could also try cleaning the maf and throttle body .
Also the baffle inside the fuel tanks have been known to come loose , its there to prevent the fuel from sloshing away from the pickup while turning sharply or stopping.
what happens if you cant turn it anymore and only get .92 volts
like I said...anywhere from .7 to 1.0 vdc is fine, no need to dremel anything.........it's a comnplete waste to try to set it to some mythical setting of .92 or .98 the ecc iv programming is not fixed on those two voltages
