high idle

[miecow]

my 90 3.1 is idleing very high, if you put it in gear and drive it, it will go down to normal but jumps back up here and their.. i just replaced the throttle position sensor could it be another bad sensor ? thanks for any help

might have a bad idle air control valve, or a vacuum leak somewhere.. check all your hoses/connections

also, if the problem wasnt happening before the TPS was changed, it probably just needs to be adjusted..

[miecow]

how do you adjust the tps?

on mine its pretty much screw it on and plug it in
