    My 92 K1500 350TBI Need Help. It starts and idles fine, will run no problem around town and on the highway, But when i turn it off go into a store and return, its hard to start and misses badly at first but then will run fine, bad gas milage.

    Sounds like maybe a bad fuel pressure regulator on the tbi. do a fuel pressure test and leak down test on it.
