So i bought my wife a 95 sc1 with a blown head gasket. i replaced the head and did all the work. i replaced the vacuum manifold because the lines broke. i got it all back together and now it has a high idle and has a check engine like for codes 12,22,24,35,45,49. code 49 says to check the IAC but i unplugged that and the bitch started screaming at 6k i plugged it back in and its sittin at about 1500. any one have any advice on wtfs going on ? any help would be really appriciated thank you in advance.

 

vacuum leak.!

 

I'm willing to bet one of those original vacuum lines are still leaking
