95 mustang 3.8

Hi, I'm new to this site and hoping to get to the bottom of my problem. So I have a 95' 6 cylinder 3.8L, I had the engine replaced after a friend of mine blew it up. (long story). Anyway, the new/used engine had an idling problem and bad fuel economy. I went to Autozone and had them run the code...

i recently got a 95 v6 and the rpms hang when shifting gears and when i push in the clutch the rpms go from idle to almost 2500 any ideas whats wrong? need help asap thanks

I have tried to find the ground wire but nothing seems to work. Can some one help me plz. It will light up but only when i push the light switch in. Anyone has any suggestions.

hi i have a problem with my gear shifter going to the "2" when i try to put it in "D" (Drive), if that makes any sense so when I drive the engine just revs up like its in the wrong gear. Well i guess it is in the wrong gear. can someone help me please ?

I have had like 2 of these cars 94 and a 95 same engine 3.8, the first i smashed it into a pole. I chopped the front clip , replaced it, made sure it was balanced and welded it into place., came out nice i have some picutres somewhere of the project. drove it for like 3 years,Took the engine...
