1. Wil the map sensor from the 94 work on the 92 engine cause whwn I plug the hose into the throttle body it revs way up ?
2. On the throttle body next to the little nipple on wheee the map sensor line goes where does that vacum line supposed to run to?
3. The car ideals around 2 rpms when cold then after 20 mins it goes down to a grand but it is burning so much gas burning realy rich? Have skunk 2 exhast from the cat back. But that won't make that much of a diffenexe wil it

 

Easiest thing to do would be to swap on a '94 - '95 D15B7 throttlebody.
