so i just bought a 90 s/c with the 5spd... drove it home.. it was idling at 3k and the brakes were really hard and the abs light would come on when you would hit the brakes....this is my first ford.... and i am impressed on how quick the car was even not running in tip top shape... but i figured it was idling high because of a vacuum leak. so i tracked down as many hose i could see. and they all seemed to have a home... but i looked at the map sensor and there looks to be a spot for a line and the repair manual says that 89-90's had a map... and the vacuum diagram under the hood is useless and the one in the book it the same thing... so i was just wondering if anyone knows on were the map sensor would hook up to.. and yes i did check the iac... and it was within spec.. teh guy i bought it from was throwing parts at it it looks like since the iac and the tps looks brand new.. thanks...
