hey guys new to the site and wondering if you could help me. i have a 97 f150 with 330 k on it. the truck was running great till it blew a hole in the passenger side exhaust manifold. the check engine light came on during the drive home guessing it was because the o2 sensor was no longer getting a proper reading. i patched the manifold (only because i live in the sticks and parts can get hard to come by and take a long time to come in) and unhooked the battery to clear the codes. now the truck idles really rough and has a bad hesitation and no power at all any clues what may be going on?
