So after 6 loooooooooong years my stang started today for the first time. (actually the second but it was only for about 10 min) But now I have a list of problems that popped up. Idle hangs sky high between shifts or anytime after applying the throttle. It hangs for 7-8 seconds then slowly creeps down, then drops to about 500 and the motor bogs and brings itself up and idles fine after that. Grinding gears between shift. The clutch is brand new and the trans came out of a 98 that hit a tree in its back right half, but it doesn't do it every time, and it isn't every gear up and down. Sometimes it will be 1-2, or maybe the 4-5 and it happens on the 2-1 rolling at 3mph. Possibly part due to the idle hanging? God awful whining noise from under, can't tell if its trans or rear. I'm not super worried about it at the moment, I had an 80 malibu for years that I crushed the pinion putting it back together and it whined something terrible and it took a supercharger to tear it apart. Speedo is way off, almost 15 high. Anyone have any advice?
