Motor Swap Issues - 97 into an 02
Alright so I've successfully swapped my motor. I got a 97 NPI for 400 bucks because I blew the bottom end of my old 02 motor. I know its a decrease in power, I just need transportation and a mustang that sounds like... well a mustang. So here are the issues I'm having.
The car starts and runs for as long as I want it to, however... The idle is high. It's sitting at like 1500 at all times. And if I rev the engine up to say like 4,000 it stays up there at 4,000 and gradually falls back to 1,500. When I say gradually, I mean like over 10 seconds.
Another thing is, my headers are getting red hot. They are glowing orange. And it's not every header. Only 2 on the passenger side.
My alternator isnt working properly either, but this is because the clip that goes into it is broken. I have a new one on the way but I'm not sure if this could account to my idling problem.
Any help or advice would be great and very helpful. Thanks.
