I recently accuired a 94 auto bird. Apparently someone had removed the SC and forgot what goes where. So car had to be delievered by flatbed ($100 for 100 miles) as it wouldnt hold idle and stumbled when driven. I replaced all the cracked vaccum line i found and put them in what I believed was the right place. I lost my old digital code reader with my last SC while crossing the county. So I went oldschool and used a jumper wire and a voltmeter. Anyway it runs much better with no check engine light. I happen to find a blown fuse 30A, and a lost vaccum hose that I'm stumped over. Now all that left engine wise that I know of is stumbling at more than 5psi boost.
