91' prelude si

i have a prelude w/ an idle problem. it revs up and down at idle. theres a sensor facing the car in front of the throttle body, coolant goes in and out. i had to have the lines brazed because of holes rusted through. could this thing be causing any of my problems? theres a screw on the end is this an adjustment screw? i need some help on this guys.

i think that is the tps-throtle position sensor(correct me if i'm wrong) and it is your problem fix the line and try again.

i fixed the lines some time ago, just wondering if i just need a new one. also being that it has run messed up should i reset the ecu? how do i do it? thanx.

i need help on this, i will hate to put in the shop if its easy to fix. does anyone have any ideas?

sounds very much like your TPS sensor to me as well, replace that first, and see if it keeps hapenning.

also if that doesnt fix it it could be an intake manifold gasket and you could try and spray carb cleaner around it and it will change the idle

where is the TPS located? not sure if im looking at the right thing.

Are you positive it's the TPS? If not you might just need to change your air filter.

i took the wire off of the TPS and it idled fine just at a higher RPM.does anyone know if i can just get the sensor or do i have to buy the whole throttle body?honda says i've got to buy the whole thing.also is there another place to get it rather than honda? thanx for all ya'lls help.

im pretty sure they arent sold seperatly, but check out www.hondaautomotiveparts.com also, they may have it.
